This song is absolutely not about a criminal. It is about two people in love, she loves and cares about him more than he does her. It seems like he is an alcoholic. She knows he is just using her but she thinks she can change him.
Cuz I know where the cops hang out,
I know where you'll be found,
I know what you're all about.
I know when you're going down.
I think these first two lines are saying she knows the town so well, and she knows him so well.
