Danziger Bridge shootings
On the morning of September 4, 2005, six days after Hurricane Katrina struck New Orleans, members of the New Orleans Police Department (NOPD), ostensibly responding to a call from an officer under fire, shot and killed two civilians at the Danziger Bridge: 17-year-old James Brissette and 40-year-old Ronald Madison. Four other civilians were wounded.
