Full Opinion (html_with_citations)
Mr. Tsutomu Shimomura claims that an officer with the Denver Police Department (Wade Davis) and an agent with the Transportation Security Administration (Kendra Carlson) made an arrest without probable cause and conspired to fabricate grounds for the arrest. For these claims, Mr. Shimomura invoked 42 U.S.C. § 1983 and Bivens v. Six Unknown Named Agents of Federal Bureau of Narcotics, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971), alleging that Officer Davis and Agent Carlson violated the Fourth, Fifth, and Fourteenth Amendments.
1. Did Officer Davis have qualified immunity (arguable probable cause) for the arrest? Officer Davis arrested Mr. Shimomura for assault after seeing him push his roller bag toward Agent Carlson. Mr. Shimomura contends that Officer Davis lacked qualified immunity in determining that probable cause existed. Thus, we must decide whether Officer Davis enjoys qualified immunity.
We conclude he does. Even if probable cause had been absent, Officer Davis would enjoy qualified immunity if probable cause had been at least arguable. In our view, probable cause was arguable because Officer Davis saw Mr. Shimomura push his roller bag toward Agent Carlson, observed her reaction by trying to avoid contact, and watched Mr. Shimomura move rapidly away. These observations could reasonably lead Officer Davis to believe there was probable cause involving an assault under a Denver city ordinance. Thus, Officer Davis enjoys qualified immunity on the claim of unlawful arrest.
2. Did Mr. Shimomura plead a plausible claim against Agent Carlson for fabrication and withholding of evidence to justify the arrest? Mr. Shimomura claims that Agent Carlson violated the Fourth Amendment by fabricating evidence and withholding exculpatory evidence to justify the arrest. On these claims, we must decide whether the allegations plausibly im*352 plicate Agent Carlson in the decision to arrest Mr. Shimomura.
We conclude they do not. Agent Carlsonâs conduct could not have caused the arrest because it would have taken place after the arrest. Accordingly, we conclude that Agent Carlson is entitled to dismissal of the unlawful arrest claim.
3. Did Mr. Shimomura plead a plausible claim of a conspiracy preceding the arrest? According to Mr. Shimomura, Officer Davis and Agent Carlson conspired to violate the Fourth Amendment by making the arrest without probable cause. We must decide whether this claim was plausible based on the factual allegations in the complaint. In our view, the claim fails under this test because Officer Davis arrested Mr. Shi-momura within seconds of the alleged assault. Mr. Shimomura has not pleaded facts showing a plausible opportunity for Officer Davis and Agent Carlson to conspire in those few seconds.
4. Did Mr. Shimomura plead a plausible claim involving deprivation of procedural due process? Mr. Shimo-mura claims that the false arrest, initiation of false charges, and conspiracy deprived him of procedural due process under the Fifth and Fourteenth Amendments. We must decide whether the allegations in the complaint state a viable claim.
In our view, they do not. The Fourth Amendment â not the Fifth or Fourteenth Amendmentâs protection of procedural due process â generally governs pre-trial deprivations of liberty. Because the sole source of protection is the Fourth Amendment, we uphold dismissal of the claim involving deprivation of procedural due process.
I. Officer Davis arrested Mr. Shimomu-ra after seeing him push his roller bag toward Agent Carlson.
In February 2011, Mr. Shimomura was going through security at the Denver International Airport, trying to catch a flight. At the security checkpoint, Mr. Shimomu-ra presented his belongings for screening. When he did, a TSA agent conducted a test on Mr. Shimomuraâs medication, using a sampling strip. Mr. Shimomura was afraid that the test would contaminate his medication. Based on this fear, Mr. Shi-momura asked about the sterility and toxicity of the sampling strip. The TSA agentâs response 'did not satisfy Mr. Shi-momura. So he asked for the agentâs supervisor.
Agent Carlson was the TSA supervisor who responded. She stated that the sampling strips were sterile for screening purposes. But Mr. Shimomura remained unsatisfied, and the conversation grew heated while Officer Davis watched from nearby.
Eventually, Mr. Shimomura was told to leave the screening area. He complied and began walking away with his roller bag, with Agent Carlson and Officer Davis following closely behind. After taking a few steps, Mr. Shimomura stopped, and Officer Davis believed that the roller bag had hit Agent Carlson. A few seconds later, Officer Davis arrested Mr. Shimo-mura. Following Mr. Shimomuraâs arrest, Officer Davis, Agent Carlson, and other TSA agents conferred for approximately 90 minutes. Officer Davis then served Mr. Shimomura with a summons and complaint, charging him with assault for pushing his roller bag into Agent Carlson. See Rev. Mun.Code of Denver § 38-93. After reviewing the evidence, the prosecutor dismissed the criminal complaint against Mr. Shimomura.
This suit followed.
Mr. Shimomura claims that he was arrested without probable cause. On this claim, the district court granted summary-judgment to Officer Davis based on qualified immunity. This ruling was correct.
A. We engage in de novo review based on our two-part test for qualified immunity.
We review de novo the district courtâs grant of summary judgment. Christian-sen v. City of Tulsa, 332 F.3d 1270, 1278 (10th Cir.2003). The court must grant summary judgment âif the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.â Fed. R.CivJP. 56(a).
We apply this standard against the backdrop of our case law on qualified immunity. This immunity protects all government employees except those who are âplainly incompetent or those who knowingly violate the law.â Lewis v. Tripp, 604 F.3d 1221, 1225 (10th Cir.2010) (quoting Malley v. Briggs, 475 U.S. 335, 341, 106 S.Ct. 1092, 89 L.Ed.2d 271 (1986)). To overcome this assertion of qualified immunity, Mr. Shimomura must show that (1) Officer Davis violated a federal statute or the U.S. Constitution and (2) the underlying rights were âclearly established at the time of their alleged violation.â Id. To decide whether Mr. Shimomura made this showing, we view all evidence in the light most favorable to him as the nonmoving party. Estate of B.I.C. v. Gillen, 710 F.3d 1168, 1172 (10th Cir.2013).
Framed under these standards, âthe salient Fourth Amendment questions presented are (1) whether [Officer Davis] possessed probable cause to arrest [Mr. Shimomura for assault]; and (2) whether extant clearly established law in [February 2011] would have placed a reasonable, similarly situated police officer on notice that no probable cause existed.â Quinn v. Young, 780 F.3d 998, 1007 (10th Cir. 2015) (emphasis in original).
B. Probable cause was at least arguable based on Officer Davisâs observation of the events.
For the sake of argument, we can assume that probable cause was lacking. Even with this assumption, however, Officer Davis would enjoy qualified immunity if probable cause had been at least âarguable.â Kaufman v. Higgs, 697 F.3d 1297, 1300 (10th Cir.2012). In our view, probable cause would have been at least arguable.
To determine whether probable cause was arguable, we must begin with the standard for âprobable cause.â Under this standard, probable cause would exist if Officer Davis had reasonably trustworthy information that would lead a prudent person to believe that Mr. Shimomura had committed an offense. Jones v. City & Cnty. of Denver, 854 F.2d 1206, 1210 (10th Cir.1988).
The threshold question involves identification of the alleged offense. On this question, Officer Davis identified Mr. Shi-momuraâs conduct as a third-degree assault under the Denver Municipal Code. Thus, we must determine what constituted a third-degree assault in February 2011.
The municipal code defined third-degree assault to include the intentional or reckless commission of an assault. Rev. Mun. Code of Denver, § 38-93. Rather than define the word âassault,â the municipal code referred to Colorado law. Under that law, third-degree assault required
In applying the municipal ordinance for assault, a reasonable police officer could have viewed probable cause as arguable. Mr. Shimomura relies largely on a video of the incident. The parties agree that this video is accurate, and Officer Davis acknowledged that it was consistent with what he had seen.
Though our vantage point differs from Officer Davisâs, we can identify at least four facts that Officer Davis would have known:
1. Mr. Shimomura was pulling his roller bag, which was between Mr. Shi-momura and Agent Carlson.
2. Mr. Shimomura stopped and moved his roller bag in Agent Carlsonâs direction.
3. Agent Carlson moved suddenly after the roller bag was pushed in her direction.
4. Mr. Shimomura walked away more rapidly after he pushed the roller bag in Agent Carlsonâs direction.
Mr. Shimomura suggests we add a fifth undisputed fact: that he and Agent Carlson had engaged in a heated disagreement.
Based on these five facts, Officer Davis could reasonably believe that Mr. Shimo-
C. Probable cause would have remained arguable notwithstanding Mr. Shimomuraâs explanation for his quickened pace and challenges to Agent Carlsonâs credibility.
Mr. Shimomura argues that his quickened pace did not suggest guilt, for he might simply have had to hurry to catch his flight. But probable cause could have existed even if his conduct might also be interpreted as innocent. See United States v. Muñoz-Nava, 524 F.3d 1137, 1144 (10th Cir.2008) (â[S]imply because an activity has an innocent connotation does not mean that it is excluded from the courtâs totality of the circumstances analysis.â).
Mr. Shimomura also argues that Officer Davis should have discounted Agent Carlsonâs description of the events, giving three reasons:
1. A heated argument had just taken place between Agent Carlson and Mr. Shimomura.
2. Mr. Shimomura denied pushing his roller bag into Agent Carlson.
3. Other witnesses did not say that Agent Carlson had been injured.
But these arguments would not preclude Officer Davis from reasonably believing that probable cause existed.
Agent Carlson and the other witnesses made their statements after Mr. Shimomu-raâs arrest; thus, these statements could not have affected the decision to arrest. And Officer Davis could see for himself what had taken place when Mr. Shimomu-ra pushed his roller bag toward Agent Carlson. In observing the incident and Mr. Shimomura accelerating his pace afterward, Officer Davis could reasonably conclude that Mr. Shimomura had intentionally or recklessly pushed his roller bag into Agent Carlson to create at least some slight physical injury.
That push might not have created probable cause for third-degree assault. But probable cause would have been at least arguable even if (1) Mr. Shimomura had an innocent explanation for walking away more quickly and (2) Officer Davis had discounted Agent Carlsonâs description of events.
D. Mr. Shimomuraâs characterization of the video recording does not create a fact issue on arguable probable cause.
Mr. Shimomura argues that Officer Davis is not entitled to qualified immunity because the video recording is inconsistent with the defendantsâ statements regarding
E. Probable cause would have remained arguable notwithstanding Mr. Shimomuraâs allegations in the complaint and uncertainty about what Officer Davis could see.
In reaching a contrary conclusion, the partial dissent points to
âą Mr. Shimomuraâs allegation in the complaint âthat [Officer Davis] could not reasonably perceive evidence of bodily injury, such as painâ and
âą uncertainty about what Officer Davis would have seen from his angle.
Dissent at 362-63. In our view, these two points do not create a genuine fact-issue on whether probable cause was at least arguable.
Because the issue involves summary judgment, we must rely on the summary judgment record rather than Mr. Shimo-muraâs allegations in the complaint. In support of the summary judgment motion, Officer Davis stated under oath that he had seen the roller bag strike Agent Carlson in the legs. Appellantâs Appâx at 112. Mr. Shimomura responded to the motion, presenting affidavits by himself and Agent Carlson. Agent Carlsonâs affidavit said that Officer Davis had seen the contact between the roller bag and Agent Carlson. Id. at 176. Mr. Shimomuraâs affidavit was silent about what Officer Davis could see. Thus, for purposes of summary judgment, we have undisputed evidence that Officer Davis was able to see the contact between Agent Carlson and Mr. Shimomuraâs roller bag.
Mr. Shimomura denies that Agent Carlson was physically injured, and Officer Davis believed there was physical injury. Neither individual could know for certain, but the sole issue on qualified immunity is whether Officer Davis could reasonably believe the contact resulted in at least some slight physical injury to Agent Carlson. Even if Officer Davisâs belief was wrong, he would have enjoyed qualified immunity as long as his belief was reasonable. See Stonecipher v. Valles, 759 F.3d 1134, 1141 (10th Cir.) (âArguable probable cause is another way of saying the officersâ conclusions rest on an objectively reasonable, even if mistaken, belief that probable cause exists.â), cert. denied, â U.S. -, 135 S.Ct. 881, 190 L.Ed.2d 705 (2014).
In our view, Officer Davisâs belief was reasonable notwithstanding Mr. Shimomu-raâs contrary allegations in his complaint. In Mr. Shimomuraâs affidavit, there is
III. Agent Carlson could not incur liability under the Fourth Amendment for an unlawful arrest because her alleged misconduct would have taken place after the arrest.
Mr. Shimomura argues that Agent Carlson violated the Fourth Amendment by withholding and fabricating evidence to justify the arrest.
We review de novo the district courtâs grant of a motion to dismiss for failure to state a claim. Christensen v. Park City Mun. Corp., 554 F.3d 1271,1275 (10th Cir.2009). Like the district court, we must determine whether the complaint contains sufficient facts, accepted as true, to state a plausible claim for relief. Ashcroft v. Iqbal, 556 U.S. 662, 678, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009). A claim is plausible âwhen the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.â Id. In determining whether the claim is plausible, we view all factual allegations in the light most favorable to Mr. Shimomura as the nonmoving party. Tonkovich v. Kan. Bd. of Regents, 159 F.3d 504, 510 (10th Cir. 1998).
As wĂĄs previously stated, a warrantless arrest without probable cause violates the Fourth Amendment. Keylon v. City of Albuquerque, 535 F.3d 1210, 1216 (10th Cir.2008). But nothing in the complaint would plausibly suggest Agent Carlsonâs participation in the arrest.
Mr. Shimomura disagrees, arguing that Agent Carlson caused the arrest by withholding exculpatory evidence and fabricating a sworn statement that she had suffered pain from her contact with the roller bag. Officer Davis allegedly relied on Agent Carlsonâs fabricated account.
This contention fails as a matter of law because Agent Carlsonâs alleged misdeeds would have taken place after Officer Davis had already arrested Mr. Shimomura. Agent Carlson allegedly withheld exculpatory evidence and fabricated a sworn statement, but only after Officer Davis had already initiated Mr. Shimomuraâs 90-min-ute detention. That detention constituted an arrest as a matter of law. See Manza-nares v. Higdon, 575 F.3d 1135, 1148 (10th Cir.2009)
IV. Mr. Shimomura has not pleaded a plausible conspiracy claim based on the Fourth Amendment.
Invoking 42 U.S.C. § 1983, Mr. Shimo-mura also claims that Officer Davis and Agent Carlson violated the Fourth Amendment by conspiring (1) to make the arrest without probable cause and (2) to fabricate their accounts for the initiation of criminal charges. We affirm the district courtâs dismissal of these causes of action for failure to state a claim upon which relief can be granted.
A. We engage in de novo review, considering the plausibility of the allegations in the complaint.
In reviewing the dismissal, we engage in de novo review. See p. 353, above. The ultimate question is whether Mr. Shimo-mura had alleged specific facts showing (1) an agreement and concerted action between Officer Davis and Agent Carlson and (2) an actual deprivation of constitutional rights. Tonkovich v. Kan. Bd. of Regents, 159 F.3d 504, 533 (10th Cir.1998); Snell v. Tunnell, 920 F.2d 673, 701 (10th Cir.1990). Conclusory allegations of conspiracy would not suffice. Tonkovich, 159 F.3d at 534.
B. For the arrest, Mr. Shimomura has not pleaded facts creating a plausible claim of conspiracy pri- or to the arrest.
The conspiracy allegations in the complaint involve conduct before the arrest. Thus, on the claims involving conspiracy to justify the arrest, we confine our review to the allegations involving conduct preceding the arrest. These allegations involve six facts
1. Officer Davis saw Agent Carlson communicate with Mr. Shimomura in an âincreasingly hostile and intimidating manner.â This conduct included Agent Carlsonâs refusal to contact her supervisor or provide her supervisorâs name, angry threats to remove Mr. Shimomura from the airport, order for Mr. Shimomura to âget the hell outâ of the TSA screening area, and statement that Mr. Shimomura had accused Agent Carlson of stealing. Appellantâs Appâx at 11-12 ¶¶ 18-20.
2. Officer Davis refused to put Mr. Shi-momura in contact with Agent Carlsonâs supervisor. Id. at 12 ¶ 21.
3. Officer Davis and Agent Carlson threatened to have Mr. Shimomura arrested if he did not leave the*360 screening area âin two seconds.â Id.
4. Officer Davis and Agent Carlson âcrowded Mr. Shimomura in a threatening mannerâ and followed him âclosely and aggressivelyâ as he left the screening area. Id. at 12 ¶¶ 21-22.
5. Officer Davis and Agent Carlson âknewâ that (1) Mr. Shimomura had not committed a crime, (2) there was no probable cause for Mr. Shimomu-raâs arrest, (3) Agent Carlson had been following Mr. Shimomura âtoo closely,â and (4) Agent Carlson had become even âfurther enragedâ when she walked into the roller bag. Id. at 14 ¶ 28.
6. Officer Davis and Agent Carlson believed that Mr. Shimomura should be criminally punished for questioning TSA screening procedures. As a result, Officer Davis and Agent Carlson took âjoint and concerted actionâ to arrest Mr. Shimomura. Id. at 15 ¶ 29; Id. at 13 ¶ 24.
For the sake of argument, we can assume that Mr. Shimomura has pleaded facts reflecting an agreement and concerted action by Officer Davis and Agent Carlson. But the alleged agreement could not plausibly have preceded Mr. Shimomuraâs arrest. The video reflects the incident, which unfolded only a few seconds before Officer Davis detained Mr. Shimomura (constituting an arrest).
It might have been theoretically possible for Officer Davis and Agent Carlson to conspire to arrest Mr. Shimomura without probable cause. Perhaps Officer Davis and Agent Carlson decided to arrest Mr. Shimomura even before his belongings were screened; or maybe Officer Davis and Agent Carlson conspired in the few seconds between the roller bag contact and Mr. Shimomuraâs arrest; or perhaps Officer Davis and Agent Carlson knew and understood one another so well that they immediately formed an unspoken agreement to unlawfully arrest Mr. Shimomura. 'But Mr. Shimomura does not allege facts that could plausibly explain how Officer Davis and Agent Carlson might have conspired in the moments preceding the arrest.
Accordingly, Mr. Shimomura has not pleaded a plausible § 1983 claim for conspiracy to arrest without probable cause in violation of the Fourth Amendment. We affirm the dismissal of this claim.
C. The district court did not err in disallowing amendment of the Fourth Amendment claim.
In responding to Agent Carlsonâs motion to dismiss, Mr. Shimomura included a footnote requesting âleave to amend should the Court find his Complaint deficient.â Id. at 121 n. 1. Though the district court suggested that Mr. Shimomura might amend the complaint, the court ultimately prevented amendment by making the dismissal with prejudice. Id. at 218, 229.
Mr. Shimomura alleges that the district court abused its discretion by preventing amendment of the complaint. We disagree. Mr. Shimomura alleges in the complaint that he was taken into custody by Officer Davis, not Agent Carlson. See id. at 12. Thus, amendment of the complaint would have been futile. In these circumstances, we conclude that the district court had discretion to make the dismissal with prejudice. See Brereton v. Bountiful City Corp., 434 F.3d 1213, 1219 (10th Cir.2006) (âA dismissal with prejudice is appropriate where a complaint fails to state a claim under Rule 12(b)(6) and granting leave to amend would be futile.â).
Finally, Mr. Shimomura claims deprivation of procedural due process under the Fifth and Fourteenth Amendments. The Fifth Amendment prohibits the federal government from depriving a person of âlife, liberty, or property, without due process of law,â and the Fourteenth Amendment extends this prohibition to the states. U.S. Const, amend. V; Id. amend. XIV, § 1.
On these claims, Mr. Shimomura alleges that Officer Davis and Agent Carlson withheld exculpatory evidence, fabricated incul-patory evidence, and engaged in a conspiracy. The district court dismissed these claims, reasoning that they âeffectively mirror[]â Mr. Shimomuraâs claims under the Fourth Amendment. Appellantâs Appâx at 220. For this ruling, we engage in de novo review. See p. 353, above. In exercising de novo review, we uphold the district courtâs dismissal because . the Fourth Amendment applies rather than the Fifth and Fourteenth Amendmentsâ Due Process Clauses.
Mr. Shimomura is correct in asserting the constitutional requirement for probable cause before he could be arrested or charged. Wilkins v. DeReyes, 528 F.3d 790, 805 (10th Cir.2008). But this right is protected by the Fourth Amendment, not by the Fifth or Fourteenth Amendmentsâ rights to procedural due process. The Supreme Court has held that â[bjecause the Fourth Amendment provides an explicit textual source of constitutional protection against ... physically intrusive governmental conduct, that Amendment, not the more generalized notion of âsubstantive due process,â must be the guide for analyzing these claims.â Graham v. Connor, 490 U.S. 386, 395, 109 S.Ct. 1865, 104 L.Ed.2d 443 (1989); see Albright v. Oliver, 510 U.S. 266, 274-75, 114 S.Ct. 807, 127 L.Ed.2d 114 (1994) (plurality opinion) (stating that the right to be free of arrest and prosecution without probable cause is governed by the Fourth Amendment, not the constitutional protections for substantive due process). We have applied this holding when the alleged denial of due process is procedural rather than substantive. See Becker v. Kroll, 494 F.3d 904, 919 (10th Cir.2007) (â[W]e find Albrightâs reasoning regarding substantive due process equally persuasive with regard to the Fourteenth Amendmentâs procedural component.... The more general due process considerations of the Fourteenth Amendment are not a fallback to protect interests more specifically addressed by - the Fourth Amendment. ...â).
It is true that âat some point in the prosecutorial process, due process concerns can be sufficient to support claim under § 1983.â Id. at 920; see also Pierce v. Gilchrist, 359 F.3d 1279, 1285-86 (10th Cir.2004) (â[A]t some point after arrest, and certainly by the time of trial, constitutional analysis shifts to the Due Process Clause.â). But Mr. Shimomuraâs factual allegations do not cross into the due-process realm.
In Becker v. Kroll, 494 F.3d 904 (10th Cir.2007), we âacknowledge^] that the Fourteenth Amendmentâs protections encompass harms to liberty outside the scope
Because the Fourth Amendment provides the sole source of constitutional protection, Mr. Shimomura has not asserted a valid claim of procedural due process. As a result, the district court properly dismissed the claims involving procedural due process.
VI. Conclusion
The district courtâs judgment is affirmed.
. In the complaint, Mr. Shimomura also invoked the First Amendment. But the First Amendment claim is not involved in this appeal.
. Mr. Shimomura points out that the video does not show the earlier argument in the TSA screening area, does not contain audio, does not show Mr. Shimomuraâs or Agent Carlsonâs face, and barely shows Officer Davis. But Mr. Shimomura does not contest the accuracy of the video.
. Mr. Shimomura relies on Baptiste v. J.C. Penney Co., 147 F.3d 1252 (10th Cir. 1998), to oppose qualified immunity for Officer Davis. In Baptiste, a police officer searched the plaintiff for stolen merchandise after watching surveillance video of a suspected theft. Baptiste, 147 F.3d at 1254-55. We concluded that the police officer was not entitled to qualified immunity because the video did not suggest that a theft had occurred. Id. at 1259-60. Mr. Shimomura's circumstances are different, for the video recording does not preclude a reasonable belief that a crime (assault) had been committed. Thus, Baptiste does not preclude qualified immunity for Officer Davis.
. Mr. Shimomura also contends that Agent Carlson incurred liability as an arresting officer because she had "acted in concert with Officer Davis to effect the illegal arrest lacking in probable cause.â Appellant's Opening Br. at 35. This argument is identical to Mr. Shimomuraâs argument underlying his conspiracy claim, which we reject below in Part IV.
. In Manzanares we stated: "As the Supreme Court has noted, it has never held a detention of 90 minutes or longer to be anything short of an arrest. [The defendant] points us to no case, and our independent research reveals none, construing a detention of 90 minutes or longer as an investigative detention.â Manzanares, 575 F.3d at 1148 (citation omitted).
. On the cause of action under the Fourth Amendment for unlawful arrest, Agent Carlson also asserts qualified immunity and unavailability of a Bivens claim. We need not reach these contentions.
. On the conspiracy claim, Agent Carlson denies the availability of a Bivens cause of action and invokes qualified immunity. We need not address these arguments. The conspiracy claim against Officer Davis and Agent Carlson was brought under 42 U.S.C. § 1983, not Bivens. Therefore, we need not reach Agent Carlson's Bivens argument. And because the conspiracy claim is facially deficient, we need not decide whether Agent Carlson is entitled to qualified immunity on this claim.
.In his appeal briefs, Mr. Shimomura alleges that Officer Davis failed to deescalate the increasingly hostile situation. But we decline to consider this argument because it had not been raised in district court. See United Steelworkers of Am. v. Or. Steel Mills, Inc., 322 F.3d 1222, 1228 (10th Cir.2003) (noting that we will decline to consider factual arguments that had not been raised in district court).
. Agent Carlson also makes four other arguments: (1) an adequate post-deprivation remedy exists; (2) Agent Carlson is not subject to the Fourteenth Amendment because she is not a state actor; (3) a Bivens action does not exist for claims involving airport screening or violation of the Fourteenth Amendment; and (4) Agent Carlson is entitled to qualified immunity. We need not address these arguments because the claim against Agent Carlson is deficient on other grounds.
