Something even more simple is the charge of disorderly conduct. Often referred to in some states as disturbing the peace. Below is the Indiana definition:
(a) A person who recklessly, knowingly, or intentionally:
(1) engages in fighting or in tumultuous conduct;
(2) makes unreasonable noise and continues to do so after being asked to stop; or
(3) disrupts a lawful assembly of persons;
commits disorderly conduct, a Class B misdemeanor
Low level crime, but it will send a message if the clowns inside the rallies who insist on being a distraction. Jail them and let them bond out after they get a shower.
..Something even more simple is the charge of disorderly conduct....lower level Crime but it sends a message...
However, fringe lunatic liberals and Bernie supporters wear a disorderly conduct Charge as a badge of honor.
