Like you have any evidence he "got his pistol".-
"I don't know why you are treating me like this. The only thing I have done is carry a pistol into a movie."
"I fought back there, but I know I wasn't supposed to be carrying a gun."
"All I did was carry a gun."
"I carried a pistol with me to the movie because I felt like it, for no other reason."
"When I left the Texas School Book Depository, I went to my room, where I changed my trousers, got a pistol, and went to a picture show. You know how boys do when they have a gun, they carry it."
Nah, no evidence. Those quotes are all fake. In fact, I'm not sure we have any evidence Oswald ever existed. I personally think the WC invented him because they had no viable suspect at all.
I don't know what your real-life job is or was, betting I'm willing to bet a substantial sum it didn't involve the law.
