Only two weeks ago, after months of public pressure, the Chicago PD released the dashcam of Laquan McDonald being murdered by officer Jason Van Dyke. Then, only yesterday, Chicago police quietly slipped out another video of officer George Hernandez murdering Ronald Johnson, by shooting him in the back as he ran away.

The latest video to be released is from an incident in the Far South Side police lockup and shows officers repeatedly tasering University of Chicago graduate Philip Coleman and then dragging his limp body from the cell.

Coleman was not a criminal, but he was experiencing an apparent mental crisis when he began to attack his mother in December of 2012. When police arrested him, Coleman was brought to a hospital where he was given a drug to make him calm down.

According to officials, Coleman's death was the result of his reaction to that antipsychotic drug, which certainly can kill people. However, an autopsy showed that Coleman experienced 'severe trauma' while in custody. His body was covered in bruises and cuts, from the top of his head to his lower legs and there is video showing him being repeatedly tasered.
