Its the way things work in the real world.
Works wonders everywhere its tried.
Any government that protects criminals and lets them prey on the law abiding is illegitimate.
That would be a government that restricts gun ownership and requires registration. Like the Philippines, which has one of the lowest rates of guns in the hands of private citizens in the world =>
The registration of the firearm shall be renewed every four years. Failure to renew the registration of the firearm on or before the date of expiration shall cause the revocation of the license of the firearm. The firearm shall be confiscated or forfeited in favor of the government.
