Bonanza - Season 7 Episode 20 Peace Officer

While Sheriff Coffee is in Saint Louis, the Morrisey bunch decides to work off excess energy by wrecking the saloon in a violent spree. When Deputy Bill Harris tries to arrest them, they hit him on the head with a whiskey bottle, accidentally killing him. All of them get away except Cliff, who is put in jail. He refuses to say the names or locations of his friends. Mayor Garrett holds an emergency meeting of the Virginia City town council. They hire legendary lawman Wes Dunn, as the temporary sheriff. He is a humorless man who is determined to restore order in town. He beats Cliff almost to death to find out where his friends are, but Cliff will not say anything. Meanwhile, Hoss finds Chuck, a wounded gang member. When he tries to take Chuck's gun away, he shoots Hoss. Joe goes with Dunn to find the other men. He thinks Dunn is a hero until he sees him murder one of the suspects in cold blood.
