Fox News legal analyst Andrew Napolitano claimed Thursday that a well-trained slingshot marksman could stop a shooter with a semiautomatic weapon. During a segment on Fox & Friends the morning after 17 people were killed in a high school shooting in Florida, Napolitano suggested that the U.S. could prevent school shootings by moving towards "the Israeli model" where certain schoolteachers "are armed and quietly trained" to use firearms effectively.

Fox & Friends co-host Ainsley Earhardt then asked Napolitano to opine on the specific gun used by the Florida suspect: the semiautomatic AR-15. The same weapon was used by the perpetrators of massacres in Las Vegas last year and at Sandy Hook Elementary School in Connecticut in 2012, Earhardt pointed out.
