Why do police forces across the USA, and federal law enforcement too, do this? Such peeping seems to directly contradict the traditions and stated goals of USA government. That is, such peeping is anti-American. Individual law enforcement officers must know this. Why don't any of them refuse to do such peeping? And why does an Australian computer web site have to point this out? If I were an American law enforcement officer engaged in snooping, I would be very ashamed of myself.
