What if your name was Abu Hamza and you were a law abiding citizen but your every move was monitored merely because you shared a name with a known extremist? What if they mistook you for him.....what if you were a Bazilian plumber expat living in London that found yourself dead because of failures in the process of the watchers?
The USA and UK are both de facto Police States and they have achieved this because of the apathetic "if I have nothing to hide blah blah blah" BS attitude married to scaremongering policies founded on very dubious grounds.
You can literally get away with murder but woe betide anyone that commits a crime against the State, it's tyrannical at best.
