I have an answer that will be most helpful.
If there are any tea party members who are burly motorcycle bikers, as well as being patrotic, ENCOURAGE them to be at tea party rallies. That will SCARE any troublemakers away.
It always works in Hartford when I go to tea party rallies, guys from a CT motorcycle group shows up. On April 15th, they took care of two gate crashers who tried to crash the tea party rally.
We were at one tea party where some big belligerent loser kept taunting the speaker. Finally four or five big people just went and stood beside this idiot while someone videotaped the taunter. He shut up. But the videographer followed him around for the rest of the time that he was at the gathering, which, it turned out, wasn’t more than about another half hour.
The taunters don’t like being videotaped. Makes identification of them easier, even though most of them are from somewhere else. They aren’t neighbors or friends who might have an opposing view, which is fine. Rather, the taunters are out to do anything they can to make front page news.
