The plain-clothes officer charged with photographing the suspect, however, was answering a call of nature when Mr Menezes emerged and did not have a free hand to operate his video device.
As a result, no reliable visual identification was made. The officer reported to colleagues that a male of the appropriate age had left the building, but advised that it would be worth someone else looking to obtain a positive identification.
Scotland Yard's gold command nevertheless declared a code red, and placed a team of heavily armed officers on high alert.
Contrary to subsequent reports, he was not wearing a bulky coat or carrying a bag. In keeping with London's spell of warm summer weather, he wore a light denim jacket.
Nor did he, upon arrival at the station, vault the ticket barriers - as claimed - in an attempt to evade his plain-clothes pursuers.
Instead, the leaked documents say, he used his season ticket to get through the barrier, collected a free newspaper from a nearby rack and proceeded calmly down the escalators, breaking into a run only when he saw that a train was preparing to depart.
Upon boarding the train, however, he was approached by a group of the police officers. One seized him while a second discharged 11 shots from a hand-gun at point-blank range.

Not with stupid gung-ho fuckwits like these guys in charge.
