Are police getting worse or are we just catching more of the bad ones on tape?
There have always been police , military, and guards who abuse the authority given them ; the proliferation of small cameras is allowing their bad behavior to be proven ,unlike earlier times when they could lie and intimidate witnesses.
Then there are the petty bureaucrats ,crooked politicians, lying salespeople,and all other criminals who may meet justice because a recording exists of their offenses.
Civilized people will have to develop a new balance of privacy rights versus camera use.
