This March, Florida state legislators passed a law that allows local sheriff’s departments to train school faculty to carry concealed weapons on campus, a measure President Donald Trump has repeatedly supported. The arrangement is formally known as the Coach Aaron Feis Guardian Program, which was named in honor of the football coach who died while protecting students against an active shooter at Marjory Stoneman Douglas High School.

Florida law does not require licensing of firearm purchasers or registration of the weapons, only mandating that concealed weapons must be permitted. This means data is only kept for concealed firearms, which means nobody really knows how many unconcealed firearms there are.

Missouri State Congress overrode the veto on Senate Bill SB656 last Wednesday with a Republican supermajority, eliminating previously-required training to obtain concealed carry permits and strengthening the right to use force in situations where an individual fears for one’s safety. It’s unclear how the new law will affect concealed carry reciprocity agreements with other states.
