Good for him for raising a ruckus and getting arrested! Going to court is just too damn expensive and time-consuming. Let the fuckers know to their faces that what they're doing is unconstitutional and that not everyone in their community is a fucking Christian!
I hope he doesn't have to pay court fees or get a felony charge. If the meeting hadn't officially started, then what was he disrupting? It's not against the law to disrupt prayer. Ask Fred Phelps!
