Why would they need ammo if they can't get a gun? Ohhh yeah because criminals get their things through illegal ways. Therefore, a background check for ammo will not prevent them from loading their illegally obtained firearm."There’s actual no check to make sure people don’t have the ammunition," Daley said. "So, you could get denied a background check for a weapon, walk into a gun shop down the street and purchase as much ammunition as you want, and no one would know any different."
