They're getting scared, and when people get scared, stupid things get done. In this case, a guy filming a Joe Sestak rally got, as NRO's Battle '10 put it, "Harassed, Intimidated, Potentially Assaulted:"
Looks like somebody picked up the camera and tossed it to the ground... and on a tactical note? This is precisely why YOU ALWAYS WORK IN TEAMS OF AT LEAST TWO. One person films - actively - the event; the other person films - passively, and hopefully unnoticed - the person filming the event. That way you remove ambiguity. Still: nice people that Joe Sestak has supporting him, huh?
