Also, I think officer's should be required to carry malpractice insurance (similar to doctor's), and qualified immunity should be thrown out. This would give insurers a strong incentive to drive-out the cops that are prone to committing assault, battery, and unnecessary property damage. I guarantee you an insurer with a profit motive isn't going to just ignore 13 use of force complaints against an officer.
Such a scheme would also make it harder for bad officers to move a city or state and continue abusing the public elsewhere. Their insurance premiums would remain too high.
