2nd that! When I was in school during the 1960s we had “assemblies” in the gym. Entertainers came and performed in shows that included some type of educational value. One time a team of fast draw people came and that was the exact message that they taught us.
There was a very high crime rate in parts of the country who did not have adequate law enforcement in the years following the civil war. But people facing off in the streets in some sort of fast draw contest was an invention of the entertainment industry.
I think I went one of those same assemblies.
