Gallup conducted the new poll Sept. 17-18, the two days immediately after a shooting at the Washington Navy Yard in Washington, D.C., in which, apparently, a lone gunman — a government contractor and former Navy reservist — went on a rampage, killing 12. Much of the news coverage has focused on the shooter’s questionable mental state in the days, weeks, and even years leading up to Monday’s events.

The January 2011 trends reflect public opinion shortly after a massacre in Tucson, Ariz., in which six people were killed and 12 others wounded, including U.S. Rep. Gabrielle Giffords.

Drug use remains the third-highest-ranking factor in gun violence, according to Americans, although, at 37%, the proportion blaming it is down five points from January 2011. Closer to three in 10 blame violence in movies, video games, and music, as well as extremist views on the Internet, and lack of building security. Now, as in 2011, relatively few — less than 20% — put heavy blame on inflammatory language by prominent political commentators.
