The Sun makes fun of it, and so do I, but of course the would-be suicide bombers have a point. They do have rights.
Such as the one to a fair and impartial trial, rather than a kangaroo court. Or the right to be arrested without unnecessary force, rather than simply be shot on sight, as would have happened in many a Middle Eastern country. Or the right to an attorney, paid for by the state, who will be struck off if he doesn't do a good enough job representing you. Try that in Saudi Arabia. Or the right to complain about any perceived maltreatment by the police, after which both a plethora of activist groups and an independent committee will try to get to the bottom of things. Hell, you even get your troubles printed in a non-state controlled newspaper (for the sake of argument, we'll assume Rupert Murdoch is not a one man state yet).
Western values don't equate to lawlessness or impotence. On the contrary. The arrests in England yesterday are a fine example that the west can combine its humanity with decisive action, if needs be.
