firearms were so primitive that an armed person would be lucky to kill two people before someone could get to him and stop him.
It's all relative and though primative by our perspective, the latest and greatest by theirs. They were certainly aware of firearms evolution as well as weapons. They were not fortune tellers but knew that they wolud continue to evolve. Really doesn't matter as they were and are in the spirit of their use. ....
In the future, someone will be asking the same question about Ray-Guns or whatever comes down the pike. ....
Be Safe !!!
