Let's stop for a moment to clear our heads from number-implosion.
Fact: The death of one honest cop at the hands of one dishonest scumbag is intolerable. And an average of one cop per state killed in the line of duty would suggest that "intolerable" is going on far too often. Better judges are needed, the kind who throw away the key rather than listen to the bleeding heart tree huggers who want Danny The Cop Killer paroled because he's turned his life around. Violent offenders shouldn't be hunting our police officers, end of story. The cops need more and better training, more and better ballistic vests, and more and better people wanting to become cops.
Police officers are likely to kill more innocent people than criminals are to kill innocent people. The single MOST alarming fact coming from 2010 is that crimes committed by cops are on a meteoric rise. Name the crime and cops are doing it at record numbers.
