The guy (or someone with the same name) is a registered user on Mountain Project, though he's never contributed anything there.
Years ago, drugstores in Wyoming had handguns in the case next to the antacid tablets. A friend bought one for a lark in exactly that situation. He happens to be an upstanding citizen, but it wouldn't have been any harder for a complete whacko to purchase the same weapon along with his Tylenol.
When it comes to ease of acquisition, it isn't a whole lot different today.
