So 3 guns each instead of 12. That should sort things out.
"After several months of debate, the Guatemalan Congress approved the Weapon and Ammunition Control Law, considered essential to reduce violence. The regulation reduces to one the four licenses previously granted to each citizen to buy armaments, and they are able now to buy three weapons instead of 12, as previously established."
This, on the other hand, HAS to be an April Fool.
