MINNEAPOLIS (AP) — A shooting at a Catholic church full of schoolchildren in Minnesota has prompted calls for gun safety legislation. But translating action into policy may be difficult in a state that mirrors the nation's partisan divisions and split opinions on how best to prevent mass shootings.

A day after , Minneapolis Mayor Jacob Frey on Thursday called for a statewide and federal ban on certain semiautomatic weapons and high-capacity magazines. If others don't act, Frey suggested, the city may act on its own.
