Philidelphia Police Beating

It's hard to even understand the state of mind of Philadelphia police officer's during the time of the beatings. Obviously, there is a history of tension between citizens and officers with two previous cases of police brutality and three officer deaths that year. Although it is difficult to determine what happened in the video of the cops, they did not need to have over three cops to each person being arrested. The video clip of the police beatings seems to be a reminder of the Rodney King case. The chief of police always states that these types of actions are unacceptable, but what type of disciplinary actions will these officers receive?
