Three activists from the Black Lives Matter movement in Washington, D.C. shared new information alleging that a "culture of violence" exists within the Metropolitan Police Department.

At a Friday morning news conference, the group's information asserts that MPD promotes "aggressive police behavior" but encourages behavior that may heighten the chance of a D.C. Police officer "fatally injuring someone."

These activists are calling for action from D.C. Police Chief Peter Newsham and Mayor Muriel Bowser.

The group in a release cited examples of shootings MPD officers have been involved in including those of Rafael Briscoe in 2011, Darius Jamal Murphy in 2013, Terrence Sterling in 2016, Isabelle Duval in 2017, and Timothy Williams in 2017.

Sterling, 31, was an unarmed motorcyclist that was fatally shot in Sept. 2016. According to the U.S. Attorney's Offce for the District of Columbia, the MPD officer who shot and killed Sterling will not face charges.

Additionally, the release states another example of a gun case that was dismissed by a D.C. Superior Court judge based on an internal investigation by MPD.

The probe by the department is connected to MPD officer Vincent Altiere, who was seen wearing an offensive t-shirt while he was in court testifying in the case. According to the release, the t-shirt contained violent and white supremacist imagery linked with the Seventh District "Powershift" team.
