Friend was arrested for flipping someone off

Location: Arkansas

Hello! I live in a small town that has had a very heated political cycle. City council meetings have seen 200+ people in town with less than 1,000 people. There is an individual who is making enemies with much of the town over him feeling left out. He is threatening legal action on every business and person who does not cater to his will.
During the last council meeting my friend flipped him off while walking outside to smoke. This did not hinder the meeting, nor did the mayor stop talking while it happened. None of the council members knew it had happened till after the meeting. The police followed my friend outside and arrested him for disorderly conduct. His court date is scheduled for the beginning of the year. I’ve heard giving the bird is protected under the first amendment. Is this true? Can he get these charges dropped?
