Many activists have been screaming about the escalating violence being carried out by police departments around the world. Of course the anti conspiracy crowd says that there is no problem...well there is a problem and it is becoming chronic.
Communities where incidents like this occur need to rise up and confront their local district attorneys and demand justice and absolute adherence to the letter and spirit of the law. When an officer resorts to this flagrant abuse of power and actively sets about to conceal their crime they become violent criminals and should be adjudicated as such.
No one is above the law, if it protects some at the expense of others it is broken.
