De Menezes execution and accountability

Just what will it take for the Met police to be accountable for its execution of a n innocent man. A jury yesterday found the met police force guilty of putting the public at risk under Health and Safety laws.
The question remains why weren't any armed officers prosecuted by the CPS over the matter? What of the brass? Cressida Dick who was in charge of the shambolic operation escaped any censure or indeed prosecution. Just what do we have to do in this country to hold the police accountable? How many others have to be executed by incompetent officers before the Menezes family gets any justice?

Following the verdict, Ian Blair, the commish, very swiftly appeared before the cameras and stated he wasn't going to resign. Why not?
Remember the lies on 22 July 2005: Menezes jumped over a barrier; he failed to stop when asked by police; he was involved in terrorism etc.
The lies given by the police means we can't trust them ever again when it comes to matters such as terrorism or the use of armed policemen.
The police escaped prosecution despite their ineptitude resulting in the loss of an inncoent Brazilian going to work, lying to the public and media, covering up the truth. Whatever happened to the CCTV in Stockwell station? How convenient that it wasn't working on the day. The whole episode stinks of incompetence, negligence and brutality.

Why do some Brits persist in questioning De Menezes' status in this country following his execution? I have heard some morons claiming he would be alive if he had gone home upon the expiration of his visa. However, the police would still have executed him regardless of the endorsement on his passport.
Why does immigration bring out the worst in Brits?
The prejudices really do come out whenever any protagonist in the news isn't from these shores. Idiots.
