High-capacity ammunition magazines are the common thread that runs through most mass shootings: giving attackers the ability to fire numerous bullets without reloading. Last week's attack in Arizona joins a long list of mass shootings made possible by the easy availability of high-capacity ammunition magazines: Columbine, Virginia Tech, Luby's, Stockton, and all too many others.

Earlier this week, Representative Carolyn McCarthy (D-NY) and Senator Frank Lautenberg (D-NJ) announced plans to introduce federal legislation to ban high-capacity ammunition magazines. A similar ban on high-capacity ammunition magazines was in place for 10 years as part of the now-expired federal assault weapons ban.

Here are just 10 of the U.S. mass shootings that involved high-capacity ammunition magazines.
