The Texan Season 1 Episode 26 Letter of the Law

Longley rides to the rescue when four gunmen bushwhack a man riding in a buggy. Longley takes the man to a nearby ranch house, but neither the owner or the town doctor wishes to assist the wounded man, a judge scheduled to preside over the trial of the local land baron. When Longley reports the shooting to the sheriff, the lawman can't find any evidence to support the Texan's version of events - or the judge himself for that matter.
