May I introduce you to my friends
The Foreign Intelligence Surveillance Act of 1978 and
The PATRIOT Act of 2001. The combination of those two effectively
is a warrant for the whole US population.
I agree that the vast, vast majority have no involvement in terrorism or such and therefore have 'nothing to fear' from government surveillance. However equally they have a right to privacy, up to and including from the government. The whole issue is that the US and UK governments appear to have moved from 'snooping on the bad guys who might do something wrong' to 'snooping on everyone just in case a few of them might do something wrong'. There's a world of moral difference between those two statements.
