This is so dumb it beggars belief. Yes, prohibited people are not allowed to buy ammo. However, anyone can go anywhere and buy ammo with nothing more than an ID, and that's only an age check. Do these senators think Walmart is running a background check on me when I pick up a box of 12-gauge?!
Saw an amusing video showcasing the ammo cops had confiscated from gangbangers. These guys often had 3-4 different types of ammo in the same magazine. If they can't afford to visit Academy for a box of 20, they sure can't afford vending machine prices.
Wrong hill to fight on you idiots.
