Killed isn't the only thing that a dopey police officer can cause. I remember another harrowing story of someone trying to help at a biking accident ending up in solitary confinement with breathing issues for two days.
google santa clara county jail, and see how many people they killed last year.. and only one of those murders was investigated and 3 guards are on trial. all others are written off.. mentally handicapped inmates with no family, easy target for sadist guards.. and no accountability.
