I watched a very disturbing video the other day. In 2011, a gang of thugs attacked a mentally ill homeless man for no apparent reason. The whole incident was caught on camera, and there were many witnesses - unfortunately people were too scared to step in and save the man's life. All the while he was pleading with them to stop, and calling for help. And they killed him.
Despite the video evidence and audio recording of the incident, the killers were not sentenced, and were allowed to walk free. This is a complete disgrace to humanity.
Here is the video:
