It's very difficult to portray one's character as being part of a law enforcement organisation. Personally I'd suggest just doing it as part of a private story alongside some like-minded friends as there's no guarantee that random role-players will play along with it even when it's done well and makes a lot of sense.
I've yet to see a role-playing community that lacked an alarming number of role-players who decide that their character can conveniently start a brawl in the middle of a populated settlement or commit a crime in broad daylight only to have no accountability for their actions.
It's a shame, but a lot of villains simply aren't willing to play nicely. Of course there's also people playing city guards who go out of their way to abuse their power and then have no consequences for their actions either.
