We're ALL biased.  We're only as aware and smart as the last data dump that hit our brains.  But what needs to happen with law enforcement is to change its strategic focus.  This is pie in the sky, but so was human flight at one point.  A criminal mindset was carefully crafted by specific circumstances.  We are ALL products of our culture.  That's why Americans don't speak French.  The old violent response to  bad behavior is still alive and thriving in our culture.  But you notice we're not putting a broken down car (criminal) into a garage (prison) and close the door for ten years and expect the inmate to be somehow "cured" of their criminality.  In fact they picked up some tips while rubbing elbows with the prison's 'finest.'  We incarcerate at a rate that is far, far higher than any other "industrialized" country in the world.  People do what they're taught, from an age so young they don't remember learning it.  Education frees all humans - black, brown and white.
