I encourage you to read Brendan O’Neill’s splendid essay on the conviction of Abu Hamza for talking rubbish here. The case of Abu Hamza is a recent and egregious example of how the British government is suppressing free speech in the name of waging the War on Terror. And, I might add, it's far more disturbing than the case of a university telling a faculty member not to post those infamous cartoons on his office door.
