Gun, AR-15

In this Thursday, July 26, 2012 file photo, an AR-15 style rifle is displayed at the Firing-Line indoor range and gun shop, in Aurora, Colo. A new poll shows a majority of Americans favor stricter gun laws, and most believe schools and places of worship have become less safe over the last two decades, according to a poll conducted by The Associated Press-NORC Center for Public Affairs Research both before and after last week’s mass shooting at two mosques in New Zealand.
