I said a verdict of lawful killing so i was talking about Duggan of course, De Menezes was an open verdict after the judge banned an unlawful killing verdict. Maybe you should read up on it. If you did, you may realise they are very very different.
I agree that trying to have a debate with you is pointless, since neither you or I were party to the evidence that the decision was based on, and those who did see all the evidence have made their decision regardless of me or you (or our prejudices).
They are wrong, on more occasions than they should be. But this was a lawful killing that was correct. That's what the jury, who unlike you, heard all the evidence, decided.
The death of Jean Charles de Menezes was an issue where you should put your efforts to make sure it doesn't happen again.
This was someone reaping what they sow, nothing to get upset about. It is proven to be a lawful killing which will and should happen again in the same circumstances.
