Yes, that's why it would take a mass law enforcement raid 10 years to remove all illegally owned guns in AMERICA ALONE. You think America has the leanest gun control laws? How about the middle east, where $10 USD gets you an AK-47 with three magazines and a box of ammunition? How about the hundreds of black market arms dealers who obtain and sell illegal weapons? How about arms dealers that are international? Another thing; how are you going to state that there's more of a chance of you dying in a car crash than to a gun crime, while your original argument was "Why do you think there's so many school shootings?" I'm sorry, but that's seems an awful lot like gun violence to me, so either you're a troll, or you don't even know what to believe.
