I've tried using SendAssaultAlarm() on the crime faction, but this only works if there happens to be a nearby guard, and also prevents the player from successfully sneaking.
I've also tried Game.GetPlayer().SetAttackActorOnSight() which should get everyone in the entire game to attack the player but this seems to do nothing at all.
How can I get faction guards to arrest or attack the player if I've added a bounty?
