I think the motive for defunding police might be to more easily usher in androids, and drones, as well as increased surveillance of everyone.
The Sheeple who can't flee the areas with no police will beg for technological solutions, and those solutions are ready to go.
Watch 10 videos on current android tech. watch another 10 on drones. Surveillance just requires a lot more camera. China has 100's of millions already.
Actually I was listening to Rush Limbaugh host this a.m. and a caller had the first reasonable explanation for defund the police. He said what'll happen is that as PD are reduced and defunded there will will a cry for help. In comes the Federal Govt. with the new Gestapo, or whatever brownshirts they'll set up. And with no local PD there is no one to stop any Federal agency from running rampant in your city, county, or State. There will be no barrier between us and the Feds. Then it's a short step from the Feds to a Globalist force.
