Stop goofing around with tragic mistakes

Sometimes I wonder if there is or should be a standard of how to classify depths of mistakes. I was somewhat shocked to read that the Met was found guilty in shooting goof. A goof? If Charles de Menezes had survived a minor wound, perhaps it would have been a GOOF. This was on the scale of major FUCK-UP. OK? You don't fucking shoot someone without FIRM EVIDENCE that he is who you think he is. Suspicious actions a terrorist does not make. I know there was a great deal of pressure to crack down on potential terrorist threats. But shoot-to-kill MUST have a firmer basis before being ordered. A shooting of an innocent is not a goof. Not in my style book.
