The Roy Rogers Show S01E06 - Badman's Brother

An outlaw named Stu Trumbull is idolized by his younger brother Larry. As a result, when Stu steals the money that was raised for the school fund and ultimately kills a man in his getaway, Larry tries his best to keep Roy, Pat, and the sheriff off his trail. After Larry aids his brother in getting away, Roy tries to convince him that being loyal to his brother even after breaking the law isn't always right.
