Outlaws were the criminals in the Wild West. While there were nowhere near as many bank robberies as the films will show, the Wild West did attract thieves and murderers. This is because there were no official laws yet. Someone could commit a crime in one town, then become sheriff in another town!
Billy the Kid was an outlaw and gunslinger in the Wild West. He is known for being a thief and for killing several men, including two deputies as he escaped from jail. He was only 21 years old when he was shot dead by a sheriff.
