I thought the whole structure of our justice system was that the state, with its unlimited resources and time, should be limited in how it handles cases.

That's why you can't be tried for the same crime twice, because the state can outwear and outlast any lawyer or defendents coffers.

It's also why prosecutors offices aren't supposed to go back on cases they already closed, because their resources are unlimited and they could push for higher sentences over and over again until it finally cracks, or they find a judge they like.

You can argue all you want about how Krasner sucks or how the cops sucks, but no government entity should be able to continously try any American citizen until they get the verdict they want.
