That would indeed be true, if we were in possession of all the facts, and it is patently obvious to most of us that we clearly are not.
You are right, we don't know all of the facts. We may never know all of the facts. This type of crash will always happen in aviation, operators make mistakes, technical failures occur etc. But in this case, so much more went wrong to cause 11 deaths. Many other air shows and public events will take place before the AAIB reports. There are lessons already that can be taken away from this. Even if event organisers are already reconsidering the risks to surrounding areas, that is a start.
What a daft question.
