To be fair. Im sure the police wanted to do their jobs. But were held back from doing so by their political bosses. The police gets a black eye each and every time they are are made to stand down during incidents like this and they dont like such bad publicity.
Sowing distrust of the police is an Alinskyite tactic. I'm sure the political bosses of the cops being told to stand down know this. It's a win-win for the radicals, driving a wedge between their political opponents and the police.
Don't blame the cops so much; go after the politicians instead. I think a few pro-Trump rallies at their houses will send the right message, no matter what happens.
