A deeply divided nation. Vicious politics. A shamelessly partisan media. A president loathed by half the populace. Smuggling and gang warfare along the Mexican border. Armed citizens willing to stand their ground and take law into their own hands....

That was America in 1881. All those forces came to bear on the afternoon of October 26 when Doc Holliday and the Earp brothers faced off against the Clantons and the McLaurys in Tombstone, Arizona. It should have been a simple misdemeanor arrest. Thirty seconds and 30 bullets later, three officers were wounded, and three citizens lay dead in the dirt.
