Constitutional Right to Bear Arms without Restrictions: We’re Number 1
The United States is one of just three countries in the world that have the right to bear arms as a constitutional protection. The other two are Mexico and Guatemala. Further, the United States is the only country with a right to keep and bear arms with no constitutional restrictions. At one time, six other countries (Bolivia, Costa Rica, Colombia, Honduras, Nicaragua, and Liberia) had a constitutional right to bear arms, but they have all repealed those guarantees.
