Wow, flip_flop.
Just re-read the post of mine you picked out. I can't see what's controversial about suggesting questions should be asked about what went wrong, rather than shrugging and brushing it under the carpet. They're the police, not the stasi.
If you take a public inquiry as an attack on the police, then I find that slightly weird.
To clarify, though, here's where I'm at. It's been suggested that the people to blame (if any) are the senior officers who provided the intelligence, rather than the officers who fired the shots. That may well be true.
It might also be true that it was entirely the fault of the officers who did the shooting - for all we know, one of them could have gone mental and lost his cool, firing a shot and provoking his colleagues into doing the same. It might come down to a few of them being grossly unprofessional.
I very much doubt that. But that's what the inquiry is for. If the police did nothing wrong, they'll be absolved. I'm not pre-judging them. The only person doing that, flip_flop is you - demanding a verdict of accidental death because it's mean of us to put the poor policemen through a proper inquiry.
