I'm starting to think it would be better to have police shootings automatically heard in a different region or bumped up to federal court rather than at the local/state level to minimize these kinds of conflicts of interest. I don't know. Maybe even a special prosecutor should always be used in police shootings for this precise reason.
I'm trying to view this from the perspective of the prosecutor. Even if the police really, really promised not to retaliate, I still can't see how it's not a conflict of interest. What if the officer is acquitted and remains on the force? Is the prosecutor going to be able to use that person as a witness? (I recognize there's technically no conflict between prosecuting someone and using them as a witness, but it's still an awkward situation). In addition, prosecutors and police are on the same team almost all the time. For example, if the police have evidence favorable to the defendant in their possession, the law considers it the same as the prosecution having it in their possession. They discuss investigative strategies, charging decisions, and work together regularly.
To me, having a prosecutor prosecute a police officer from the same jurisdiction is no different than having that prosecutor prosecute someone from their own office. It just seems...I don't know, like a flawed system?
Man, what a mess.
