I Fought the Law

 is a quest in Fallout: New Vegas.

Quick walkthrough
Talk to Eddie and ask if there is anything to do. He will tell you that he wants you to deal with Chavez, another convict that has set up camp south of the NCR correctional facility. When you head to deal with Chavez you can A)Kill him or B) use [Speech 30+] to persuade him to leave. Report back to Eddie when Chavez is dealt with. You'll recieve spare powder and dynamite for your work.

Eddie then asks you to get rid of a suspicious merchant that has set up shop West of the NCRCF. When you talk to the traveling merchant you can A) [Intelligence 6+] see through the merchant facade and he tells you he's a bounty hunter after the PG's B)[Speech 30+] again he'll tell you he's a bounty hunter but if you ask him to pay a toll another [Speech 30+] option will appear. He will ultimately give up and go away. You may also kill him and take his things after. Report back to Eddie

Next he'll want you to go to Primm and find out what the NCR are planning to do about the convicts at NCRCF. Go there and talk to the locals or go West just outside of Primm and talk to the Lt. Hayes, or both.

-Lieutenant Hayes- if you ask what the plans are for the NCRCF he'll just tell you that its classified. But after you speak to the locals an option to betray Eddie and team up with the NCR soldiers on the raid on NCRCF.

-Primm Locals- (You may have to kill some Convicts first) Locals are locate in Vicki&Vance Casino. Talk to Johnson Nash and you'll have a few options. [Speech 30+] [Barter 30+] or pay him 100 caps. He'll give you the info needed and you can go back and report to Eddie.

If you decide to help the NCR soldiers, you will fight against the PG's at the correctional facility and gain good reputation with the NCR and become disliked by the Powder Gangers.

If you help Eddie and the PG's you can either stay and fight or run away. If you fight you will become well liked by the PG's and become hated with the NCR. In this case, you can also simply kill Lieutenant Hayes, and take the instructions he has on him, and then report back to Eddie.

If you have a bad reputation with the Powder Gangers, you will be attacked on sight by Eddie's bodyguards and named NPCs (Hannigan, Dawes, etc), even if disguised as a Powder Ganger. Killing Eddie will automatically fail this quest.

Bugs

 * Even if you successfully complete the siege on the prison and get NCR back in control Mr. New Vegas will still say the siege failed on Radio New Vegas.
 * Even after you complete the siege on the prison and kill Eddie, in the ending-story (after you've finished the game) it will still say that the facility was never retaken by the NCR.
 * When assisting the NCR, the NCR troops will happily rush the administration building, ignoring the cell blocks and visitor center. In turn, the powder gangers in the cell blocks and the visitor center will not exit during the assault, requiring the player to manually clear them out. This may be the cause of the above two bugs, as not killing all of the gangers may make the game detect the assault as a failure. It may also be caused by having Sgt Lee die during the mission and not being able to report back to him.
 * After helping retake the Correctional Facility it was suggested by Sgt Lee to go back to Primm to talk to Lieutenant Hayes, but Lt Hayes will not be in Primm. Hayes may be in a camp North of Nelson.
