From the police report:
The man was identified not only by the people there filming for him, but also by a business card he had on him that had his picture on it. The card read, "TheANDREWMEYER.com "Speak my mind." I asked him if he was Andrew Meyer and he said, "Yes, I am."
Meyer was transported to the Alachua County Detention Center by my myself and Officer Vinson. Meyer stated he just wanted Senator Kerry to hear what he had to say and that he was upset when he ended the questions without being heard. Meyer stated, on the way to the jail, "I am not mad at you guys, you didn't do anything wrong, you were just trying to do your job." Meyer was laughing and being lighthearted in the car, his demeanor completely changed once the cameras were not in sight. Meyer did ask, at one point, if the cameras were going to be at the jail.
Unsurprisingly, this lunatic had been spurred to action by one of the more commercially successful conspiracy mongers, Greg Palast:
In addition to raising the issue of vote fraud in 2004, Meyer asked Kerry about the possibility of impeaching President Bush and whether the two former opponents were members of the secret Yale University society Skull and Bones. Meyer said his questions were based on Greg Palast's book "Armed Madhouse," a year-old muckraking anti-Bush bestseller that Meyer waved wildly as he was being subdued by police.
Shamans and charlatans such as Palast, who under the guise of "investigative reporting" blatantly manipulate troubled minds with "hidden" insights based on half-truths and innuendo (and profit handsomely from it), ought to be held financially liable when the increased levels of anger and paranoia they are fueling become manifested in destructive or violent acts committed by their readers.
