This is a classic example of bad / misleading marketing on behalf of a reform movement. The "Defund the Police" movement has been poorly named. Yes, there are absolutely some folks on the extreme who truly want to disband the police and live in a place without police, but by and large, the major of people who are supporting this movement mean something else:
Defund == defund the CURRENT police organizational structure (militarized, etc.), reallocate funding for things like homeless support, domestic checks, etc. to other departments better suited to handle them, and KEEP a policing organization which is responsible for a much narrower scope of duty with a reformatted training program, etc.
It should be branded "Reboot the Police", not "Defund the Police"...
