He's proved it. I mean,he let some bogus deadline pass to fire racist cops? That was intentional. Why did he never alert the media of that loophole? Even if he didnt know- that could be even stupider.
He watched 8 cops surround a mentally ill guy with a single pen knife and felt "threatened"? kill him with 16 shots?
Remember when the Sheriffs who beat that guy who looked just like Steve Martin's character in the Jerk to death? The blond Chief fired them and had them arrested.
San Francisco has no rules. Ed Lee? He should be ashamed. He's mostly been impotently silent.
