Of 86 state gun laws passed in the six months since the Newtown school shootings, states have both tightened and loosened access to guns, says USA Today. Lawmakers in many states broadened both who can carry a gun and where they can carry it. States including Colorado and Maryland tightened access to guns, Arkansas and Mississippi eased restrictions, and many other states issued rules whose impact could be debated either way. Since Newtown, the national death toll from guns has topped 5,000, according to a crowdsourced data initiative by online magazine Slate and the Twitter feed @gundeaths. That is an average number for the past five years. There have been 10 mass shootings since Newtown that killed 44 people. The most recent came last week at Santa Monica College in California, in which a gunman killed five people. Four people – including the gunman – died in a murder-suicide shooting Thursday in St. Louis.
