Man Attacks Cop With A Chain In San Franshitshole

A video was uploaded to Twitter showing very patient cops in San Francisco trying to deal with a man with a metal chain, most likely on Fentynol.

The man lunges towards a cop and strikes him in the head with the chain before the other cops pounce on him. The question is why didn't the cops at least taser him before the cop was injured? The answer is the city protects the dangerous and endangers the good guys.
