Over Memorial Day holiday in Chicago, I joined more than two dozen other journalists with the New York Times to report on every single shooting victim in the city that weekend. The rate of gun violence has gone up this year in Chicago, and the holiday weekend usually sees a spike in shootings. In all 64 people were shot that weekend, six of them fatally. Senior video journalist Brent McDonald and I worked shifts to cover on video as many of the incidents as we could over the four days. The collective work of all the New York Times reporters, photojournalists and editors resulted in an incredibly rich multimedia project that is devastating in its impact.
