A reporter for the St. Louis paper the Riverfront Times has a message for all the members of the Tea Party movement he smeared with false accusations of political violence: "I have no regrets."

Chad Garrison penned a blog post last week speculating that a member of the Tea Party had firebombed the office of Rep. Russ Carnahan, D-Mo. "Given what we know of [the perpatrator] - 50, white, angry - he certainly fits the demographics of a Tea Party member," Garrison wrote. " "On second thought," he added, "maybe he's not a Tea Party member. Firebombing your opponent's office seems a little too, um, sane for that group."

But it turns out the man was actually a disgruntled former Carnahan staffer and blogger for the left-wing site Talking Points Memo, not a member of the Tea Party. Members of the movement asked Garrison to retract. His response: lighten up, wingnuts.
