This is the title of an entry in another guy's weblog. Mr G Allen is he says just an ordinary American who heard about a local protest, went along to take photographs and find out what was all about.
Later he received a legal letter saying he was a member of the protesting group. The letter accused the group of illegal activity such as making bomb threats and demanded that 'his' organisation stop behaving illegally.
An employee of a nearby coffee shop who just happened to be walking past the protesters received an identical letter. He and she had been followed to their cars and had their number plates photographed by private detectives. This was, apparently, the sole 'evidence' the lawyers had.
OK, you've guessed. This is the Church of Scientology again, making new friends.
