Many cities across the country have faced an increase in gun violence in recent years, especially since the start of the COVID pandemic. That's true in Washington, D.C., the nation's capital, where, on Friday, a shooter fired multiple rounds from a high-powered weapon at and around a school close to pickup time, wounding four people and sending panicked parents, students, nearby residents and pedestrians running for cover. The incident provoked a massive law enforcement response and national news coverage before the suspected gunman was found dead of a self-inflicted gunshot wound hours later. Remarkably, no one other than the shooter was killed, but it was just one of several episodes of gun violence that same day in the District of Columbia and around the nation.
