Armed police roaming the streets don't solve car break-ins. I specifically mentioned car break-ins in my comment below[1]. I want the police department as we know it to be disbanded so we can have real solutions to real problems.
No one is saying stop solving crimes. Minneapolis may disband their police department, and get out of the union contract. But they aren't going to stop solving crimes. The lack of crimes being solved currently is explicitly mentioned as a reason for disbanding current police department, and looking for smarter solutions.
