A series of demonstrations are planned in D.C. today following a grand jury’s decision not to indict officer Darren Wilson in the death of unarmed teenager Michael Brown.

Black Youth Project 100 began a planned 28-hours of non-violent demonstrations this morning outside Metropolitan Police Department headquarters, calling for “action against police brutality and lack of police accountability and transparency.”

“The 28 hour demonstrations and direct actions seek to signify the disturbing statistic, that according to the Malcolm X Grassroots Movement, every 28 hours a black person in America is killed by a police officer or vigilante,” according to organizers. D.C. residents are asked to participate.

The group says it will “occupy” the Office of Police Complaints at 12:28 p.m. and Councilmember Tommy Wells’ office inside the Wilson Building at 2:28 p.m. Wells, the chair of the Council committee on the Judiciary and Public Safety, will be asked to draft legislation to create a citizens review board. The group will then move to Mayor-elect Muriel Bowser’s transition office at 5:28 p.m. to make the same demand.

Black Youth Project 100 will join the National Black United Front for a demonstration at 7 p.m. in Mt. Vernon Square. The group’s 28-hour demonstration will end with an education session Wednesday at the NAACP office on U Street NW.

The demonstrations follow a massive gathering at the White House, where nearly 1,000 people rallied in support of Brown, calling for justice. The teen was fatally shot in Ferguson, Mo., in August.
