Forrest Gump

Democrats don't want to abolish all police. They want to abolish local police so that the only law enforcement and information collection arm is federal. A consolidation of power to strengthen the state.
This is why democrats hate the local patrol cop, but lick the boots of every FBI, IRS, ATF, and CIA they can find.

All part of the plan, when both sides of government are divided along with people beyond repair. The current regiment is necessary to usher in socialist construct and provide the tools and ammunition to "above the law" federal entities for enforcement.
Old Joe also has the martial law flag at his disposal and has had it for months now, all just a matter of time.
