It's time we faced the fact that the Police are not and never will be on our side in any meaningful way.
Police need to be ostracized. Their families as well. Toss their spouses out of any social groups/churches to which you belong. Throw their children off of any community sports teams. Forbid your dating-aged children from consorting with the children of the police. Deny them service in your businesses. Refuse to aid and abet them in any way. Provide them with zero support. Give them no information. Isolate them in every way and at every opportunity.
tl;dr: FUCK THE POLICE
