If Obama is fixated on the "firearms" problem so much so that he has to include a question pertaining to gun ownership on a questionnaire to prospective hires, it seems to me that he will damn well turn his attention to those people who have registered machineguns/subguns. Certainly a lot of us have speculated upon what types of events could be forthcoming regarding future actions. A common retort is "we'll be grandfathered in" if, for instance at a certain point all sales of FA weapons to civilians is outlawed. What about just plain old, "turn them in or else." Or perhaps some type of "buy back" scheme. The imagination runs wild. I'd say that the large majority of people who have FA have them registered with the feds. I wonder how many have considered selling them while they can, just in case. At $3500 and up per weapon, that could be a whole lot of merchandise just waiting to find its way into some type of "black market." The possibility does exist whereas the government could condemn a segment of the population as "criminal" under specific circumstances just like they did during prohibition.
