Guns fall into the hands of the wrong people because:

(1) It is too easy for people to get guns
(2) If guns are got by the right people they can still be passed on to wrong people.
(3) A right person who has a gun, might become a wrong person in the future.
(4) Wrong people can only be identified as those who are known to be wrong people.

Is America suggesting that the yardstick for gun ownership should be whether or not they have a track record for wasting schoolchildren?

Would those who advocate ownership of firearms to put there own children into a ballot for there own children to be executed on a one to one basis for each murdered child as they do not seem to have a problem about allowing their own people to own the means to murder other peoples children.

No, I am not seriously proposing the above - I am just trying to highlight the double standards of the gun lobbyists who put their rights above other people's children but are probably hypocrites when it comes to their own families.
