Outside court, Mark Duggan's family called his death "an execution."
Mr Duggan's aunt Carole Duggan said: "For as long as it takes, God give my family strength."
She said: "The majority of the people in this country know that Mark was executed.
"We are going to fight until we have no breath left in our body for Mark and his children."
Vowing not to give up, she added: "No justice, no peace."
