Why let them? Every LEO has a bond. If instead of allowing them to get away based upon the Bond holder's investigation we start making claims to those bonds instead of suing the City, State, County, Federal Agency, we can get them off the streets. Once a LEO has a large claim on their Bond for wrongful death they are off the street, and generally out of work since the Bond holder will cancel them unless it can be proven to a jury that they acted correctly. Oh Shit! is not a defense for killing someone. I dropped my weapon and it went off is not either since they are trained on how to prevent that. Careless people should not wear, use, or carry a firearm in confrontations with the public. Thus no Surety Bonding Company is going to insure them. That makes them un-hireible by Incorporated Cities, Counties, and States, who will have to self-insure them.
