All true. Nonetheless, this guy was carrying guns and crossing the border illegally... to my way of thinking, that too is a little off.
Considering that all he was carrying was a .22 handgun and a .22 rifle, I have to doubt that he was the most dangerous sort of person imaginable.
My best guess, is that he's just an outdoor wanderer, who finds a box of .22LR cheaper than buying meat. Likely hunted rabbit, pheasant, etc to eat while wandering.
Crossing the boarder illegally? Without a doubt the only way he COULD cross with firearms.
