Investigate charges that New Orleans police officers inappropriately used lethal force against citizens after Hurricane Katrina.

Behind the enduring images of heroic rescues undertaken by the New Orleans Police Department in the aftermath of Hurricane Katrina, there is another story of law enforcement in crisis, even out of control. “Law & Disorder,” a year-long, ongoing collaboration among FRONTLINE, ProPublica and the New Orleans Times-Picayune, investigates charges that NOPD officers inappropriately used lethal force against New Orleans citizens and then tried to cover up their actions—allegations that are continuing to surface in federal court. Drawing from reports published in a real-time online investigation, FRONTLINE takes a fresh look at how the NOPD performed when the rules of civilized society collapsed.
