Congressional Democrats appeared on Capitol Hill Thursday to push for a new ban on assault weapons and high-capacity magazines.
The bill's author, Sen. Dianne Feinstein of California, started her remarks with a roster of tragedy: "Columbine. Virginia Tech. Aurora. Tucson. Oak Creek. The common thread in these shootings is each gunman used a semiautomatic assault weapon or large-capacity ammunition magazine."
After the Newtown shootings, some suggested that schools look to local volunteers to beef up security. One national organization has been doing that for years. It's called Watch D.O.G.S., and it organizes fathers to volunteer in their children's schools. After Sandy Hook, the group's strategy didn't changed. Some Watchdogs say they've just become even more vigilant. NPR's Sam Sanders has this report.
SAM SANDERS, BYLINE: Like school principals all over the country, Michelle Wise sprung into action after Sandy Hook.
President Obama's historic plunge Wednesday into the politics and realities of gun control in America has mobilized advocates on both sides of the issue.
But though his major proposals, from banning assault rifles to more stringent background checks and ammunition limits, are being rolled out in the shadow of the school massacre in Newtown, Conn., their Capitol Hill prospects remain highly uncertain given long-standing resistance to such efforts.
