Probably. I even think I know who you are thinking of.
HOWEVER, it's probably moot. The government can track what you buy on line, and that means most preppers are already on their list.
It's essentially certain that anyone who posts regularly on prepping issues is also already on their list.
Remember, preppers have officially been designated as possible terrorists, which means the government has given itself the authority to do this. They aren't even trying to hide it.
BTW: Homeland Security has purchased over a billion rounds of hollow point ammunition. There is only one possible target for this much ammo: us. Since most preppers can and will defend themselves, Homeland Security apparently thinks they will need a lot of ammo.
