Pitts, normally you just want to change to entire way the helicopter industry functions. But now you have moved up to wanting to change the way the Scottish legal system works! I think you may have a problem making your wishes come true!
Anway, there is considerable support for your point about why it has taken so long to convene the FAI, but that is just the way it is. It is not a recent decision, there was always going to be an FAI - it is required under Scottish law - only the timing was in doubt.
As to the previous decisions not to prosecute, they were of course made by parties who were close to the events, or based on their reports, and perhaps might be considered to be not totally impartial as a result. Whereas the FAI should be totally impartial with no internal axe to grind. It will be a good thing, albeit rather late as you and others have said.
