Batman works with individuals within the police he trusts, like Gordon, whether they’re at the top of the organisation or the bottom. He doesn’t trust 90% of cops, because he knows about ACAB. Keep in mind that DC Comics is a world where billionaires can be good people, so we’ve already got a fair amount of fantasy in the works. There are also unreasonably upstanding police, though just as rare.
