I Fought the Law

I Fought the Law is a side quest in Fallout: New Vegas.

Detailed walkthrough
This quest is given by Eddie at the NCR Correctional Facility in the administration building. He's the man sitting behind the desk on the second floor, surrounded by guards. Talking to him and asking how you can help out is all that is required to start this quest.
 * If you acquired a "shunned" reputation with the Powder Gangers by completing the Ghost Town Gunfight, you will still be able to talk to Eddie in order to receive this quest but assaulting anyone in the prison or gaining another level of infamy will turn the Powder Gangers hostile upon your entrance. Completing the Nipton quest, Booted or the Vault 19 quest, Why Can't We Be Friends? may provide a sufficient boost to your faction reputation, provided you're not "Vilified." If the Powder Gangers are hostile still, you can talk to Eddie by using a Stealth Boy outside the entrance and sneaking all the way to Eddie (this however might not work). Stand up and immediately talk to Eddie and the quest can be initiated. A Stealth Boy will be required each time you go back to talk to Eddie until the quest ends with the NCR confrontation. It's also possible to acquire Powder Gang simple outfit or any other Powder Gangers outfits (also including Powder Gang guard armor) to disguise yourself and infiltrate the camp, then take out everybody besides Eddie in the Administration Building with a silenced weapon. Once only Eddie is left, it's advised you save and walk up and talk to him before he sees through your disguise. Once done talking get out of there as fast as possible again.

Chavez
The first task you'll be given is to "take care" of a Powder Ganger named Chavez, who Eddie believes is setting up his own crew without permission. He is located at Powder Ganger camp south, which is just south of the prison. You can either convince him to "move on" with 30 Speech skill (35 XP) or kill him (20 XP, 80 XP total if his guards are killed). Talking to him without being able to pass the speech skill will result in combat. Killing him (and/or the other Powder Gangers with him) won't cause any reputation loss with the Powder Gangers, and interestingly, his "crew" may not turn hostile if you kill Chavez in front of them. Killing him or his crew after convincing him to move on also doesn't cause any reputation loss with the Powder Gangers. Whichever way you decide to do it, return to Eddie and let him know Chavez is handled to gain Powder Gangers fame +1.

Traveling merchant
The second task is to "deal with" a suspicious traveling merchant residing at Jean Sky Diving. If you have 6 Intelligence or 30 Speech, you can convince him to reveal that he's actually a bounty hunter by pointing out that he lacks a pack brahmin to carry supplies and protection (only the speech option provides 30 XP). You can try to shake him down for a "toll" (30 Speech required, 30 XP). The bounty hunter may attack you even after you convince him to leave, even if you are not dressed as a Powder Ganger. If the prior options fail, the merchant can be killed without Karma penalty, plus his death yields 20 XP, though he carries a stimpak and will use it if attacked. Once the merchant has been dealt with, report back to Eddie to gain Powder Gangers fame +1.

NCR attack
Finally, you'll be asked to find out about the NCR's plans for the prison. Head to Primm and seek out either Johnson Nash or Lt. Hayes. Nash will cough up the information for: Any of the skill check options will award 30 XP.
 * 100 caps with no skill check
 * 50 caps if you have 30 Barter
 * 20 caps if you have 30 Barter and appointed a new sheriff to Primm
 * Free if you have 30 Speech

Hayes will only tell you that military orders are classified, unless you already know - either by pickpocketing the "Military orders" off him, and/or by getting the information from Nash first. Once you have the information, you can either report back to Eddie or betray him to Lt. Hayes, and help the NCR take back the prison.

Side with Powder Gangers
If you report back to Eddie, he'll reward you with 1 Buffout, 1 Psycho, 1 Mentats, 100 caps, and 200 XP. He'll say that the NCR is already here, and tell you to feel free to kill some of them on the way out. As soon as you exit the building, the assault will begin, and NCR troopers pour into the facility and attack. You won't lose reputation with the NCR for informing on them; however, all the soldiers assaulting the base will be hostile to you, which will likely cause NCR reputation loss as a result of shooting back (only if you kill any of the soldiers). Alternately, if you change into NCR armor before exiting the building, the NCR invaders will be neutral, but some Powder Gangers will be hostile.

If Powder Gangers defeat the attackers you can speak with Eddie who will thank you. You will gain Powder Gangers fame +12.

Side with NCR
If you instead choose to betray Eddie to the NCR, you can choose the dialogue path with Lt. Hayes where you ask to help in the assault. He'll tell you to rendezvous with Sergeant Lee, located just to the south east of the prison (on a hill, approximately in line between Powder Ganger camp south and the prison). Once you initiate dialogue with him, he'll give you a short "briefing," and the assault will begin. The quest will end once Eddie is dead, but as the Powder Gangers will rush out into the courtyard for the battle, Eddie will most likely be one of the last Powder Gangers alive anyway. You'll be awarded 300 XP for completing the quest, and gain reputation with the NCR. The NCR reputation is gained by speaking with Lee after Eddie dies. If Lee dies during the assault, you won't gain NCR reputation.

Lee may mumble something about reporting back to Lt. Hayes after the quest has finished but, if My Kind of Town has already been completed, he will be gone from the NCR camp at Primm. You may run into him later at Camp Forlorn Hope. It is possible that Hayes and some of the troops under his command were sent to Hope, and that is why some troops at Forlorn Hope say that they got reinforced by troops from Primm.

Behind the scenes

 * This quest is a reference to the song of the same name by Sonny Curtis & the Crickets, more famously covered by the Bobby Fuller Four in 1965 and The Clash in 1979.


 * A number of cut and partially completed dialogue options exist which point towards the final portion of the quest having had additional options for helping out. In particular, a number of incomplete topics would have allowed the Courier to offer suggestions as to how Eddie could better defend the facility, including posting more guards and placing snipers on the guard towers.
 * The Courier was also being given the option to free Chavez from the prison.

Bugs

 * Completion of this quest in favor of the NCR will not register the proper result. Even though you gain the fame for success, Mr. New Vegas will report the mission as a failure, as will the ending narration.
 * Sgt. Lee may freeze on the steps to the admin building and will not finish dialogue - thus preventing NCR fame. Shooting weapon out of his hand which will turn Lee hostile but then holstering weapon immediately which will return Lee to turn friendly will unfreeze him.
 * If the player passes the Intelligence or Speech check to make the bounty hunter admit he's there to collect Powder Ganger bounties, the question "So what are you still doing here?" will still be available. If selected, he will answer, "Uh, you know, just filling up water and stuff." This response is in support of his cover story rather than the truth he has just admitted.
 * The explosions that opened the entrances for the NCR troops will not detonate mines or c4, giving an easy way to finish this quest however you will gain infamy from the NCR.
 * If the players sides with the Powders Gangers, but have neutral or positive reputation with the NCR, Sergeant Lee won't be hostile to the player or the Powder Gangers unless he see the NCR troopers getting attacked. Lee will rush to Eddie's room and stand there for the rest of the game, saying "Shut up and fight!" if the player tries to talk with him. Once the NCR troopers dies, I Fought the Law will be completed, even if Lee is still alive.
