This is a valid point that raises a somewhat separate issue. Most police don't live where they work. Police should have to live in the precinct that they serve. If you live in Cherry Hill, NJ you should be a Cherry Hill police officer, not a Camden police officer. If you want to be on the Camden police or the West Philly police or the BedSty police you should have to live there.What about cops that work in inner city areas that have a lot of gang violence? Are they to be fined every time they're involved in a shooting just because they drew the short straw and had to work a crappy post instead of in a nice, safe suburb?
That way there is no "short straw" ... you police your own neighborhood. If there is no room left on the force in the town where you live well then you need to move to an address in a precinct where they need police. People transfer for work all the time. If you don't want to move then find a new job. If you need more police in a particular precinct then you raise the pay to attract more applicants. Market based solution, right? That alone would probably reduce police shootings.
That... and a policy that restricts police from using deadly force except to prevent civilian deaths/injury, and prevents police from using self-defense as a blanket justification for deadly shootings. FWIW, I agree that docking police pay and/or increasing their hours as "punishment" is not a productive approach.
