Maybe this is a hot take but the good guy got his ass beat because the officer in the situation decided to focus her efforts on the person ready to defend themselves rather than focusing fully on the aggressors.
Literally out here. Trying to defend the aggressors from catching those self-defense pipes and in the process caused the good guy who stood up for a woman to get beat down by the aggressors
Don't do this! Focus on the aggressor! Don't try to stop someone defending themselves
