No real similarities. This wasn’t even a case of police brutality. It was a case of serious incompetence getting an accused (of very minor offenses) person killed. It’s not like they shot him or beat him. The neglected to make him wear a seatbelt (which, BTW, is illegal in Maryland). Then when the person was obviously injured they failed to get medical attention. In the future, police will make sure that prisoners be transported in the modern day “Paddy wagon” wear seatbelts – and if the person can’t breath he is rushed to the hospital.
Damage from the riot was minimal and limited to the central business district. The major disruption involved Orioles fans being told to not to leave the game early (good move, the O’s won in extra innings – dramatically since they had blown a sure win earlier in the night).
