That was my first thought as well. A worry is police officers make mistakes which leads to anywhere from hapless people getting terrorized, harmed or killed. The bad thing about AI is it'll allow police to escape responsibility. Perhaps also where a human will realize it made a mistake they can admit it and everything is okay. But if AI says you had a gun, it won't walk that back. AI said he had a gun. But when we checked, he didn't have it anymore.

In the Menezes case the cops were playing a game of telephone that ended up with him being shot in the head.
