When you escape from a jail, what exactly makes the guards hostile to the player?

According to the wiki, this is controlled by the Story Manager. Specifically, the http://www.creationkit.com/Escape_Jail event

- Hypno

That's not what I mean. When I break out of jail and put on a guard's uniform, I don't want the guards to be hostile to the player. I've tried SetCrimeGold(0) and SetCrimeGoldViolent(0). I've tried SetPlayerEnemy(false). I've tried making the guard faction allied with a custom faction assigned to the player. The guards still immediately go hostile once they see the player.

e: Oh. PlayerPayCrimeGold() is what I needed.
