1951. Interesting, 72 years ago. When talking about all the violence, shooting, guns and Cowboy and Indian shows, it’s also interesting to note that events like the Wounded Knee Massacre (1890, the deadliest mass shooting in the U.S.) had only occurred 61 years earlier.
Many of the people who carried out the slaughter, and the wider policies of genocide, might of even still been around in 1951. Their children would of certainly been. Given that context, it easy to see why TV showed a revised “feel good” history account and a morality based on might and who was quickest with the gun.
