Lawbringer

Lawbringer is a Fallout 3 perk.

Description
You will get a note from The Regulators telling you that they "require your aid in bringing the scum and pestilence that inhabit our home to justice" and ask you to report to Sonora Cruz at Regulator HQ for details. Sonora Cruz, the leader of the Regulators, will pay the Lone Wanderer for each "evil" person brought to justice (killed) and requests their finger as proof. She will pay 5 caps per finger unless the Lone Wanderer has 750 or more Karma, at which point they will pay 10 caps per finger, this is determined by your Karma before the turn-in, not after. Each finger will give the Lone Wanderer 10 Karma, regardless of their current Karma. If you are 10 Karma away from 750 and you have multiple fingers, dropping all but one and doing 2x turn-ins will net more caps.

Bugs

 * It is possible that Sonora Cruz vanishes from the Regulator HQ and does not return. Fast traveling to the HQ often spawns various combination of hostile creatures and/or robots. They are normally busy killing the brahmin outside the HQ, however they engage you upon your arrival. Due to the nature of the AI and the non-player character characteristics of Sonora Cruz, this causes her to flee from the area and not return. She can be brought back to the HQ by using the console, but must be disabled, then re-enabled to reset her scripts, or she will act continually frightened. It should be noted that if you kill whatever is outside before you enter the Regulator HQ Sonora Cruz will not flee.
 * She can sometimes be found wandering around outside the HQ building.
 * Even with the Lawbringer perk, Regulators in the HQ will hold a bounty notice saying that you're a dangerous person who is to be shot on sight for a reward of 1000 caps when having an Evil or Very Evil Karma status.
