One would presume past convictions would greatly increase the potential liability of any officer behavior involved lawsuits. Perhaps some of these municipalities will suddenly find their insurance policies dropped.

That is exactly the reason large cities self-insure.
Are you saying large cities self-insure so that they can hire officers who are uninsurable due to committing crimes?
That doesn't sound like a reasoned policy decision.
