Baltimore was named “the most dangerous city in the U.S.” in 2017. But earlier this month, the city went for a record 12 days without a homicide, the longest in three years. And it coincided with the third 72-hour Baltimore Ceasefire, which began Feb. 2.

The ceasefire’s chief organizer is Erricka Bridgeford of the Baltimore Ceasefire 365, but it is truly community led. Residents come together to have peace walks, discuss conflicts and organize sports tournaments, movie screenings and other community events. The ceasefire has been very effective at a time when the city’s police force has been plagued by corruption.
