Rodney Brown v. Matthew T. Boettigheimer, No. 21-2460 (8th Cir. 2022)

Plaintiff was removed from a political rally and arrested for violating a St. Louis, Missouri ordinance that prohibits disturbing the peace. After Plaintiff was acquitted of that charge in state court, he brought claims against, as pertinent to this appeal, three St. Louis Metropolitan Police Department officers. The district court granted summary judgment in favor of the officers, and Plaintiff appealed.
 
The Eighth Circuit affirmed holding that it was objectively reasonable for the officers to mistakenly believe, under the totality of the circumstances that Plaintiff was engaged in acts or conduct inciting violence or intended to provoke others to violence. The court explained that two of the officers had arguable probable cause to arrest and then initiate prosecution against Plaintiff meaning that it was not clearly established that doing so would violate Plaintiff’s right to be free from unlawful seizure, malicious prosecution, or First Amendment retaliation. Thus, the court affirmed the district court’s grant of qualified immunity to those officers. Further, the court wrote that the district court properly granted qualified immunity to the remaining officer because it was not clearly established that initiating prosecution against Plaintiff would violate his Fourth Amendment right to be free from malicious prosecution or his corresponding right under Missouri law.
