In videos from a block party on Saturday night, hundreds of teenagers and young adults are seen dancing in the Brooklyn neighborhood of Baltimore and singing along to the lyrics of local rappers.
As they shout and move their hands through the air, many hold up phones to record the revelry on a hot summer night.
A barrage of gunfire had torn through the Brooklyn Day party in South Baltimore, leaving two young people dead and 28 more people wounded.
Even for a city plagued by gun violence in recent years, the number of victims was staggering, representing more people than would sit in an average high school classroom.
Over the past decade, only 10 other shootings in the United States have resulted in so many gunshot victims, according to the Gun Violence Archive, a research group, though many mass shootings have taken more lives.
