Donuel.The problem goes way beyond possession of firearms. What other country would turn a blind eye to 1100 deaths caused by police shootings last year. How reliable those figures are I have no way of telling. To an outsider it indicates a very violent society.

In 2016 7100 were killed by handguns
3000 by firearms type not stated
1600 by cutting instruments or knives
400 by hammers and clubs
600 by rifles and shotguns.

Superficially a complete ban on handguns would seem sensible.
banning knives beyond a specified blade length in a public place
A complete ban on automatic/semi automatic weapons.
Restricting the magazine size of rifles.
Stringent regulations covering ownership and storage of weapons.
Since the turn of the century 9 males between 14 and 15 have shot and killed people in schools. For thus to happen the controls must be inadequate.
   Trying to weed out lunatics will never be 100% efficient. Banning guns only has impact on the good guys. The solution to me would seem to be along the lines of security(gun safes bolted down) and far tighter controls on having firearms in a public place.
   If a person needs to jump through hoops for a car license it would follow that as a gun is potentially far more dangerous then the jumps and hoops for ownership should be of a far greater magnitude.
The second amendment may allow the bearing of arms but cannot society insist that those wishing to bear arms clearly demonstrate that they are fit and proper persons to have this right? Does society not have rights as well?
