No other arrests were made?  You gotta be kidding me!  And I just don't get the philosophy of the police leaving what is obviously a hostile scene to "diffuse" it.  I'm thinking harassing a police officer when they are doing their duty to "serve and protect"  is a crime.  Arrest them all and let them deal with the criminal justice system.. That's gonna cost them money, and we all are lucky some jail time.  This outcome just emboldens the rats...
