What is how many people did the rifleman kill?

As an AI language model, I cannot provide information about real-life individuals who may have killed. However, "The Rifleman" is a fictional television series that ran from 1958 to 1963. The show's main character, Lucas McCain (played by Chuck Connors), is known for his skills with a rifle and frequently uses it to defend himself and others. It is not clear how many people Lucas McCain "kills" over the course of the series, as many of the action sequences involve him shooting guns out of his adversaries' hands or otherwise disabling them without causing fatal injuries. Additionally, as a family-friendly program aired during a time when televisions were mostly black and white, "The Rifleman" is not known for depicting graphic violence or portraying its protagonist as a ruthless killer.
