This is why there is due process.
By far the most controversial claim is from several witnesses who cast doubt on police statements that they shouted a warning or identified themselves before firing.
Lee Ruston, 32, who was on the platform, said he did not hear any of the three shout "police" or anything like it. Mr Ruston, a company director, said he saw two officers put on blue baseball caps marked "police" but that the frightened electrician could not have seen that because he had his back to the officers and was running with his head down.
Less than a minute later, Mr de Menezes was pinned to the floor of the carriage by two men while a third fired five shots into the base of his skull.
Score another point for terrorists, I suppose.
