The Rev. Al Sharpton announced Saturday a march to Washington from Baltimore would be held this month while saying he was thankful for the arrests of the six police officers charged with involvement in the death of the African-American man Freddie Gray, 25, who suffered a fatal injury while in their custody. The civil-rights activist also urged the adoption of a federal law that would require all police officers in the U.S. to wear body cameras to “protect both the citizens and the officers” in a speech at the headquarters of his National Action Network (NAN) in New York.

Sharpton discussed the important roles amateur videos have played in recent police incidents in providing immutable evidence of police misconduct. “They would have called Eric Garner a liar if it weren’t for that video. They would have called Walter Scott a liar if it weren’t for that video. These six officers would not have been charged if it weren’t for that video,” he said. “The only [person] that doesn’t want a camera is someone that has something to hide.”

Garner and Scott were both killed during confrontations with police, with videos of their deaths uploaded to various websites and viewed millions of times. Garner’s mother, Gwen Carr, and his widow, Esaw Garner, were in attendance Saturday, NAN said in a statement.
