I listen to a lot of talk radio, and one program I tune in Is the G. Gordon Liddy program. He was discussing a similar confrontation with a caller who had been stopped physically by a security guard outside a Best Buy store. Liddy, who is a lawyer, advised this man that with good representation, there is no reason he shouldn't own the very store he had a gripe with. His reason was that if a security guard puts his hands on you without a really good reason which can be documented, then he is in violation of some very serious laws.
Give a man a fish, and you feed him for a day. Teach him to use the net, and he wont bother you for weeks.
“The highest glory of the American Revolution was this: It connected in one indissoluble bond, the principles of civil government with those of Christianity." -John Quincy Adams
