Someone comes into a large room we are all in, and announces very loudly to everyone "I JUST GOT ARRESTED FOR BEING DRUNK AND IT WAS NOT BECAUSE I WAS DRUNK, THE POLICE ARE RACIST"

People are laughing, and some comments can be heard among the people in the room like "YEA, RIGHT", "THAT'S WHAT THEY ALL SAY", "THANKS FOR THE UPDATE", etc.

I don't think we would really think the comments were that inappropriate. When you go into public and broadcast something, it is perfectly acceptable for people to disbelieve you or make fun of what you said.
