Read about Radley Balko's "Rise of the Warrior Cop," chronicles the steady militarization of the police in the U.S.

To the police, civilians are citizens to protect. To the military, we are a population to be subdued. Wars can temporarily override the Constitution. When the Justice Department walks into Congress with requests for money and new laws to fight a war, it is going to get a different response than if it came in with a story about fighting crime.
To me, the most dark story is about the mayor of Berwyn Heights at whose door steps a package of drugs was delivered. Apparently a common tactic to send to a neutral address and then to collect it. SWAT team stormed the house, killed two dogs and terrorizes the family.
