A Muslim group has said it is concerned there is a new police "shoot to kill" policy in the UK following the shooting dead of a man in south London.
The Muslim Council of Britain said it was getting calls from Muslims who were "distressed" about the incident at Stockwell Tube station.

"These guys may have been some sort of plain clothes special forces," he said.

"To have bullets pumped into him like this suggests quite a lot about him and what the authorities, whoever they are, assumed about him.

"The fact that he was shot in this way strongly suggests that it was someone the authorities knew and suspected he was carrying explosives on him."

He added: "You don't shoot somebody five times if you think you might have made a mistake and may be able to arrest him."

Prof Clarke said police officers were not trained to carry out operations in this way.

"Even Special Branch and SO19 (Scotland Yard's armed unit) are not trained to do this sort of thing.

"It's plausible that they were special forces or elements of special forces."

Mr Ramm said the danger of shooting a suspected suicide bomber in the body was that it could detonate a bomb they were carrying on them.

"The fact is that when you're dealing with suicide bombers they only way you can stop them effectively - and protect yourself - is to try for a head-shot," he said.

"Take a look at the American Revolution. With a foreign army in occupation of New York, Charleston, and Savannah, with the existence of the nation at risk, most of the founding fathers defended treating with Tory civilians with due process of law, and resisted the harsher measures called for in some states."
