[Superman] What is Superman's relationship with Metropolis PD like?

We know Batman's relationship with the GCPD. Has an ally with Gordon most of the time. Some officers don't like him but most of them support his actions. Is it the same with Metropolis? Are they receptive when he flies down with a baddie for lockup?

It varies over time, though tends towards the positive. By the time his career is in full swing, he's gone a long way to build credibility with local authorities as a guy earnestly trying to help. Another advantage he has is Clark Kent, Ace Reporter; while Batman doesn't really have an excuse to be shoving his nose in people's business, it's perfectly reasonable for a reporter to be sniffing about, allowing Superman to compartmentalize that element of vigilante work from his hero persona.

There are exceptions, though. Some of the cops take the view that Superman can't be trusted, or demands greater scrutiny. Other cops could be under the influence of villains, like Lex Luthor. And sometimes, Superman manages to screw up badly enough to spoil the entire thing, like the time in the Animated Series where he gets brainwashed by Darkseid and used to invade Metropolis.
