Ms Johnson said: "I feel so sorry for the Duggan family. This is yet another death involving the police and a black person.
"People are not getting justice. The police should not be killing people."
Ms Osamor, who works at Haringey Law Centre, in Tottenham, said: "I knew Mark Duggan when he was a little boy. So little has changed over the years.
"Here am I picketing outside Tottenham police station yet again."
