Of course we do - the entire system is designed so that’s the only possible outcome. And this is the core problem - not that police do corrupt/illegal things, but the systems put in place to govern them prevent accountability or actual reform. There’s so much that has to be changed before the police forces can be.
It also puts to lie the assertion that police forces care about catching criminals. If they really did, they’d have more serious protections in place to prevent corrupt or even just sloppy cops from getting away with things like this (and risking freeing convicted criminals from jail). Instead, they have systems in place to protect dirty cops and they’re happy to hire on cops fired (in lieu of prosecution) from other police forces for abuses. In their hierarchy of goals, catching the perpetrators of crimes is fairly low.
