I absolutely understand where you are coming from. All I would say is this: PPRUNE purports to be a site for professional aviators. Many contributors both here and elsewhere, are extremely experienced individuals. We all try to understand accidents, not to see people criticised. (Every single one of us, even the very best are always guilty of human frailty!) We do it to understand. Hopefully reducing the chances of similar accidents occurring to others..
If pilots starting out in this business can pick up the odd 'nugget' from the ramblings of the KOSs, then that's a good result. If the KOSs remind themselves of things they had forgotten, then equally good. None of us have the time, nor frankly the luck, to make every mistake ourselves!
Think of these discussions as crew room chat, (which anyone can listen in to) and you may get the idea of their value?
Edited to add: KOS = Kn@ckered Old Sh1t!
