No, the fastest way to fix it is to invalidate any and all arrests and ticketing the officer performs while the camera is not functioning. Then publish when it occurs. Suddenly cameras will be everywhere.

While you cannot remove QI you can probably get away with unpaid leave when an officer is under investigation but I expect that to eventually get overturned by union activity.

Politically its radioactive, note the choices made on both sides for candidates and who got to speak at their relative conventions. If anything we will see increased funding for police with the typical wording to make it sound like we asked for it.
