Please spare us your adoration of the police.  Police are responsible for crimes every day, none of which are punished or even recognized publicly as crimes.  During the Vietnam war, I worked for the Washington Free Press.  All of us lived and worked in a communal house.  The glorious police used to break in every week or so, destroy our equipment, wreck the place.  Years later, I was standing in front of Children's Hospital in Washington with my infant daughter in my arms, waiting for a bus home.  A police car drove up to the intersection and stopped.  The civilian car behind the police car stopped.  A second police car drove up behind the civilian car and stopped.  A policeman got out of the first car, went to the driver's window of the civilian car, and shot the driver in the head.  Then the policeman got back in his car and both police cars drove away.  They knew I had seen them and didn't care.  I could go on and on, the litany of police sins is endless.  And as for danger, miners and many other categories of workers have more dangerous jobs than the police, but don't get the pleasure of breaking the law with impunity to make up for it.
