The only solution is mass, organized, armed resistance by the working class. Abolishing the police or even reforming the police is asking the American imperial bourgeoisie to backslide on their progress in placating and controlling the people.

The police are the first and last line of defense against the people, with maybe the exception of the military, but the volunteer force isn't tooled for urban warfare and is by no means large enough to put up much resistance to organized workers (ignoring the likelihood that in this situation, many would defect to the workers. Especially because you can't really do the "send them to not their home" with instant communication).

The fact that police shoot people as a reaction is something they want. It's means their lapdogs are trained well.
