What keeps bringing the "gun control" debate back to the political foreground is not all the various gun crimes that happen far too often. What does it is the legal gun owners committing mass shootings, or letting others take their guns and committing mass shootings. The problem here is not hardened criminals buying submachine guns in back alleys. Its citizens legally buying their firearms in gun shops or at gun shows and then killing, or letting others kill, us with them.
The answer isn't letting the legal gun owners convince us to get guards to protect us from the legal gun owners' guns. The answer is to make it harder for the legal gun owners to kill as many of us whenever they decide too. The percentage is minor because its rare. However the cost of each attack is far out of proportion with the frequency. Rare but incredibly costly.
