Hell no. If they're violent then get them arrested and prosecuted. Banning them from flying forever is a complete government overreach. If they're just complaining loudly and being unruly without being violent (shouting/refusing to do things) then remove them from the flight and ban them from your airline as is your right, but none of that is against the law.
