"He was disgracefully discharged from the Military, and as a matter of policy such people are meant to be added to the "no guns" list. Clearly the "no guns" list is an effective gun control..."
So maybe a change of list type from negative vetting (there's nothing to say this person shouldn't have a gun) to positive vetting (this person has applied to their appropriate local authority, who have checked out their background and decided they are a fit person to own a lethal weapon?
It works in a number of other countries, it just means that the purchaser has to plan ahead and get the clearance to own the gun before heading for the nearest gun shop.
