> Since we're presumably already talking about changing the law, we could presumably set up a system whereby those legal obligations are reduced according to those judgements.
I mean, sure, we could presumably amend the Constitution to weaken due process protections to allow that kind of collective punishment, but that's a fairly drastic measure with enormous knock-on effects.
But also, that takes much deeper and wider political support at all levels to pass than just electing DAs that will prosecute cops for crimes; if law enforcement has enough politics pull to prevent the latter, it has more than enough to prevent dismantling fundamental Constitutional guarantees just to make punishment of officers not proven to be directly involved in wrongdoing easier.
> I don't actually advocate it, but (paraphrasing) "that doesn't even make sense" isn't the most interesting response.
It may not be the most entertaining, but the proposal is incoherent on many levels, so its really the only possible response.
