Gary may be English but he has, in fact, heard of the First Ammendment.
I remember kids on the elementary school playground telling each other, "I'll call the cops on you!" It was a statement made for dramatic effect, and always an empty threat.
Gary and I got a letter last week basically telling Gary, "If you don't take down your blog, I'll call the cops on you!" It was a cease and desist letter from an attorney, but it had all the bluster, drama and false accusations of a petulant child who wants another kid kicked off the playground. It was the kind of letter that barely dignified a response except to point out the ridiculousness of it.
If the police happened to show up on our doorstep, we would be more than happy to invite them in and offer them a nice cup of tea (made by the Englishman--I'm better at the iced variety) and discuss the whole situation. Hey, one of them may even be our neighbor--we live close to the police department and know of a couple of officers who live on our street. We could get to know them a little.
Thankfully, there is no legal recourse for writing the truth on the Internet. Even the loudest kid on the playground couldn't supercede the teachers. And even hiring an attorney to harrass someone doesn't take away their First Ammendment rights.
