Brazilian probably wasn't acting or dressed suspiciously, was already restrained when shot (8 times - I thought it was 5 still...), and wasn't even identified properly because a "police officer was relieving himself" when de Menezes left his home. One leak to reveal another.
It cannot be overstated as to just how much of a cock-up this all is. Yet the powers that be - the powers that have insisted on giving themselves all the more power without any real accountability - will probably cloak themselves in silence until this all goes away. The BBC article currently states at the bottom:
"Scotland Yard and the Home Office have so far said it would be inappropriate to comment."
Translated, I read this as "Scotland Yard and the Home Office realise that anything they say could be taken down and used against them, just as the lies they've already come up have made them look foolish." But that's just me. Personally, I think that if you want power to shoot anyone dead on a mere whim, you must have accountability. If you have accountability, you'd better be prepared to take responsibility for all of your actions.
A member of the public has been shot dead after repeated police bungles and an overly-paranoid atmosphere of panic. This is not the way to run a city, no matter what threats we're told we face. I've lost track a bit - when's the public inquiry?
Furthermore, it's interesting to compare the leaked reports with the original BBC eyewitnesses and their Q&A on the shooting. From the latter:
"The police do not make their exact tactics public."
It's really time we started demanding an answer to the question, "Why not?"
