Two shootings, two different responses — Maine restricts guns while Iowa arms teachers

State lawmakers are taking very different approaches to public safety following high-profile shootings. Maine's Democratic-led Legislature gave final approval to new restrictions on guns before adjourning Thursday. The move comes six months after a deadly mass shooting in Lewiston. Iowa's Republican-led Legislature meanwhile approved allowing teachers and staff who get firearms safety training to carry guns on school property. That comes three months after a fatal shooting at an Iowa school. About 20 states have passed gun-related legislation this year, and more than half the states did so last year. Democrats generally favor more limits and Republicans more freedoms for gun owners.
