People like this are a dime a dozen. They are the "If the government tries and comes to takes ma guns 'way im gon...." type. Most of the time they are entirely harmless and it is all action fantasy. FBI keeps track of these types (they are loud) and they keep track of the inventory too. This guy isn't ever going to go on a rampage, and when the FBI knocks he will always roll over and comply. It only turns into a Waco when you accumulate a following of sorts.
