Weapons have allowed mankind to overcome the natural world, provide for self-defense, and wage war against enemies. They have also resulted in innumerable crimes, injuries, and deaths. And weapons that are concealed, as opposed to those that are in plain sight, often result in injuries and fatalities that would not have happened had the gun been obvious.
While the right to keep and bear arms is a constitutionally protected liberty, all states limit a person's ability to carry or possess certain weapons in certain situations. Each state has its own laws that establish the types of weapons that are illegal to own or possess.
