Naturally, we can rely absolutely on the finding, absolutely no question of conflict of interest, per-conception bias, proponent bias, confirmation bias or any of the other issues that arise when a bureaucracy (whether uniformed or not) investigates itself.
Of course not, but what else do we have? If there is a genuine argument for change, then the proponents of that argument need to do the ground work and prove their case. Dick Smith's rants on PPRuNe don't 'prove' anything and are only likely to harden the attitudes of those on the other side of the argument.
