Haiti
The constitution of Haiti provides citizens with the constitutional right to possess firearms at home. However, due to the collapse of a licensing system, no new licenses are issued except for ex-members of military. The Firearm registry has also ceased to exist, so most legal firearms have technically become illegal. Currently, it is unknown how many legal or illegal firearms are in Haiti.
Reading about kidnappings by Well Armed Gangs in Haiti I decided to look up their gun laws. I got this from Wiki so take it with a grain of salt. When I got to the part that says “so most legal firearms have technically become illegal” I had to pause and wonder, could that happen here in the good ole U.S of A?
