Everyone should be punished for their crimes, but proportionally and according to the law. The punishment for something he might have done in 2009 is not asphyxiation to death by a random policeman.So his criminal past from 2009 means he is not a criminal and should not be punished for his crimes? I couldn't care less what happens to the police officer that killed the black. I feel NOTHING for both these people.
This man was murdered not for any crime that he committed but because policemen in the states feel they can brutalise citizens, especially black ones, with impunity, in the course of their duty. The very citizens they are paid to be protecting.
Their is a long litany of these types of murders followed up by the acquittal of policemen by biased juries in America.
That could have been me, you or anyone else.
