Most Americans support tough new measures to combat gun violence, including a ban on assault weapons and posting armed guards at every school, according to a new Washington Post-ABC News poll.

More than half of all Americans — 52 percent in the new poll — say the Newtown, Connecticut, shootings made them more supportive of gun control; just 5 percent say they are now less apt to back tighter restrictions. Most Americans are also at least somewhat worried about a mass shooting in their own community, with concern jumping to 65 percent among those with school-age children at home.

In the poll, 58 percent of Americans support a ban on assault weapons, which expired in 2004 after 10 years as the law; 39 percent oppose it.
