Homeland Security? I don't believe that is anything more than a program title and a figurehead director. The night people, cops and crooks, keep watch over this country. Where could the nukes be hidden so a junky wouldn't find one while looking for loot and try to pawn it for a fix? Somebody is always looking someplace: there's hardly a square foot of America that isn't being watched by somebody or other on a regular basis.
"...there's hardly a square foot of America that isn't being watched by somebody or other on a regular basis."
Good lord. They're not going to put them out on the sidewalk. They coud have been smuggled in a container and secreted to any one of a million storage garages around the country. Is somebody searching all the individual storage units? How about everyones garage?
