In their current form? Well, on those occasions where we have a protest or a march, cops stop traffic and block streets for us. Cops are useful if you're white and want to report a crime or traffic accident.

Saturday protestors demanded the legalization of marijuana and immediate end to cops searching cars for drugs in Des Moines Iowa...cops lie say they see impaired driving or "smell" drugs driving while black stops by the hundreds annually in Des Moines

Shoot outs with bank robbers and mass shooters....chasing Bonnie and Clyde.....actually my dad was deputized for a day with his private pistol and 2way radio....Buck the mechanic souping up fast cars with wide tires was shot dead in the head Dexter Iowa with Blanche covered in blood crying for her dead man sat behind a huge log....Barrow & Bonnie escaped the ambush that day weeks later died inside their car filled with bullets

police are needed but they need to get back to the community. It's time for foot patrols again. And they need to lay off the blacks.
Why are black folks given much harsher prison sentences for the same crimes a whites? this needs to stop.
Ans as Bobby said the alt right groups need to be disarmed. Hell, the police need to disarm. Ban assault weapons!

Let them disarm all of the right-wing/alt-right individuals and groups. Then their work is done and they can be disbanded.
