The lawsuit alleges that the Minneapolis Police and the Minnesota State Patrol used unnecessary and excessive force to suppress people’s First Amendment rights to assemble peacefully and speak out against injustice. Peaceful protesters were teargassed, pepper-sprayed and shot with foam bullets and flashbangs to intimidate them and quash the protests. Law enforcement often fired without warning or orders to leave.
