On September 16, 2007 in Baghdad, the private security firm Blackwater USA killed 10-20 people in a shooting spree. Details are on CNN.com and MSNBC.com. Many people have commented on the inevitable nature of these killings, which arise from the privatization of the military. Blackwater USA has been involved in many such killings, always writing them off as self-defense. They tried that again this time, but no one believes them. And many people are taking a second look at previous events with similar explanations.
