Police arrested and detained several young people in Watertown, Wisconsin, on Saturday while they were preaching at a public drag queen event.  Video circulated on social media showing multiple police officers arresting Marcus Schroeder as he was reading from the Bible. One officer was recorded aggressively pulling a microphone out of his hands and walking him away in handcuffs. Nick Proell, another young Christian, was detained and removed from the venue but later released with a warning. Is this a First Amendment violation?
