If this happened at the next tea party event...it wouldn't.
The cops here served notices for three straight days on the protestors, telling them to quit squatting in a public park. It was only after they refused to move that they were moved.
Had those same notices been served at a tea party event, they'd be a non-issue because tea parties don't squat permanently on public property. They'd be gone at the end of the day anyway, likely leaving the place cleaner than when they'd arrived.
I haven’t seen anything to indicate that police would fire tear gas at a tea party event. Police I’ve seen at tea party events were relaxed and happy mostly looking away from the crowd (Some of those tea partiers were openly carrying and police were still relaxed.)
Somewhere deep in my files I have a photo of a 20 something tea partier with a mohawk covered with tattoos, carrying a huge Gadsen flag, grinning at a cop as he shows him his shoulder holster.
