Seems that British Police don't like freedom of expression. I don't care enough to agree or disagree with what these guys did, but arresting them? Now that's a police state. Thunderfoot proposed a thought experiment, burn Principia, burn the bible, people would give you disapproving looks, but burn the koran and it's the end to world peace. I wonder if the police would've responded the same way to the bible or principia?
