About the Shootout At The OK Corral. The problem wasn't that the Ungers were thugs(they were), the problem was that Tombstone was one of the first places institute a 'no guns inside city limits' rule. Sooner or later it was going to happen.
Crazy idea but maybe neighborhoods should be able to police themselves without too much outside interference. In other words if a Black Thug commits a crime inside a Black neighborhood and the Black citizens decide enough is enough and choose to handle the matter themselves then who is anyone to say whether they are right or wrong.
