Completely unnecessary, but the reality is we as humans are still nothing more than stupid animals. Since when has destroying your own city, vandalizing your neighbors, and looting local businesses ever helped? The same happened in Baltimore a few years back and I will never understand how people see these actions as any form of justice or retribution. However I will say this, the negligent officers who didn't stop the disgusting act of murder from happening should be charged for accessory and the murderer should be have the book thrown at him, life in prison with no parole or death sentence.
