Permitless carry, also known as constitutional carry, is becoming much more common in the United States. Twenty-one states have now passed some form of permitless carry, and given the overall expansion of carry rights over the last 40 years, it’s not unreasonable to imagine a future where one might be able to carry in almost any state without ever having to complete a firearm licensing or permitting course. There’s conflicting data as to whether permitless carry results in increased or decreased violent crime. Still, there is one thing that’s absolutely certain: if you choose to carry a gun without going through your state’s permitting procedure, there’s a good chance that you may end up committing a felony without even realizing it—all due to the Gun-Free School Zones Act.
