The Second Amendment right to bear arms does not mean that anyone can have any weapon and discharge it anytime they want. Gun ownership and use have limits — including age requirements, background checks, permit requirements, and restrictions on the types of firearms that can be sold.
Additionally, Florida and many other states prohibit convicted felons from owning a firearm. In some cases, convicted felons can have their right to bear arms restored, but only after a lengthy and detailed legal process.
