@BillRM,
And can you go to the hardware store and buy a stick of dynamite?
Look! Constitutional gun controls exist--the NRA's comments that the first amendment is to protect citizens from tour government is botch. You can't buy dynamite at WalMart, nor can you freely have a operational hand gernade, a STEN (or zip equivalent), a five inch howitzer (or even a 12 pound Napolean), a COBRA helicopter, a Sherman Tank, or a sawed off shotgun.
Granted these controls were enacted after a tragedy to prevent its re-occurrence (try buying a ton of ammonium nitrate and not be a farmer or in construction), but they have occurred as the result of some political demand. A demand that has become contemporary post Aurora and Newtown.
Don't get me wrong, I believe in the right of citizens to own firearms (pistols, shotguns, rifles) . However, there has to be some reason and the fact that there are already 200 million firearms out there that makes this a particularly tough nut to crack..
I personally have seven modern firearms (1900+) and four black powder ones (rifles and a Remington 44). Granted none of these firearms are wanna be assault rifles, but I see Farmerman's proposition reasonable.
Account for bullets. Ammunition has a shelf life.
I have a rifle that is barely modern (1903) that is a great shooting rifle. I don't shoot it much anymore (once a year to clean, set sights, and renew expensive ammunition) but I keep it in good shape because I just might to have to shoot an runaway elephant (I live by a zoo). If the MIB's requested that I account for my ammunition purchase records, I can present my ammo box and shooting book and range targets.
And Straw Purchasers of firearms (and ammunition) should receive federal sentences akin to a major drug dealers in a SuperMax.
