Matt Cane, General Secretary of the Metropolitan Police Federation, said: "Police officers will be stunned - but perhaps not surprised - about the utter lack of balance in the BBC Panorama documentary aired last night over the death of Chris Kaba.
"We say again the ramifications of this case remain widespread; police officers should not have their livelihoods, and their liberty, put at risk for performing what unequivocally, in this case, was his lawful and appropriate function.
"The continued use of the word "unarmed" when talking about Kaba remains scandalous when we consider how many colleagues have lost their lives because of vehicles.
"Cars are - in the hands of dangerous criminals - very much weapons.
"We note that the documentary revealed how, following the shooting, the Independent Office for Police Conduct launched what was a politicised homicide investigation against our colleague.
"And we can assure our members that this revelation will be subject to further scrutiny.
"Chis Kaba was a dangerous criminal, and this must never ignored. Sgt Martyn Blake acted within the law that evening and within his police training on that day.
"He will always have the full support of the Metropolitan Police Federation.
"As will all of our colleagues who continue to volunteer to carry a firearm in London to protect the public."
