The commissioner of the Metropolitan Police has said armed officers will start wearing video-cameras in an attempt to build trust with the community.

Sir Bernard Hogan-Howe made the announcement after friends and family of Mark Duggan reacted with fury to the lawful killing conclusion given by the jury in the 29-year-old's inquest yesterday.

In a statement, Sir Bernard said the shooting of Mr Duggan led to a "significant reduction in trust" between London's black communities and the police.

He said: “My sympathy is with Mr Duggan's family at the loss of their loved one, and with the communities affected by the consequences of his death.

“I welcome the verdict of a jury that our officers acted lawfully when they confronted an armed criminal who they believed posed a threat to them and to the public.

“But I recognise that some in the community are still angry at Mr Duggan's death.”

The 29-year-old was shot dead by an armed police officer in Ferry Lane, Tottenham, on August 4, 2011, after the minicab he was travelling in was stopped as part of a police gun crime operation.

Yesterday the jury in the inquest into his death ruled by an 8-2 majority that he had been lawfully killed, despite also deciding he was unarmed when the officer fired the fatal shot.

The Met commissioner said: “We'll begin a trial this year in which firearms officers are issued with body-worn video cameras to record the actions of officers and those they are dealing with.

“We want to see if this is an effective way to record evidence and ensure public confidence.”

Upon hearing the verdict Mr Duggan’s family and loved ones reacted with anger and started screaming and swearing at jurors.

The judge and jury were quickly removed from the court room for safety reasons as some family members began to move towards them in an aggressive manner.

Outside the court house Mr Duggan’s aunt Carole said her nephew had been “executed” and the family was shocked by the decision.

Sir Hogan-Howe said: “I know that we have much work to do with black Londoners to build trust and confidence in the Metropolitan Police.

“We are already working with communities across our great city to achieve that, and we now appeal to all local leaders to help us in that.

“We know it will take time. We know it won't be easy.”

The commissioner said he will meet community leaders in Haringey to discuss how "confidence" in the Met can be improved.
