One nation under fire: A week's glance at gun violence ripping across America

ABC News tracked who gun violence ripped across America for a week and tracked more than 900 shooting incidents -- or, a shooting every 12 minutes.

Thousands of fans gathered in Wisconsin to celebrate the Milwaukee Bucks' NBA championship, but scenes of celebration soon turned into chaos when gunfire rang out. Two shootings broke out early Wednesday in downtown Milwaukee that wounded three, sent people running for their lives and left the community shell-shocked. The shootings are only a snapshot of the skyrocketing gun violence that has swept the nation in recent months. Between Saturday, July 17, and Friday, July 23, the Gun Violence Archive tracked at least 915 shooting incidents -- or, a shooting every 12 minutes -- that left at least 430 people dead and 1,007 wounded. In total, more than 1,000 were wounded or killed this week alone. These numbers are not static, and are constantly updated as data comes in. Watch "One Nation Under Fire" on "This Week" Sunday.
