Ideally the fraud, corruption and bribery in the star chamber would be investigated by an external agency that would seek independent prosecutions. Until we can admit these issues exist and hold people to account the corrosive impact will forever filter down the rank chain*.
I know the SPA has tried to move on some cases with Service lawyers taking a more investigative role, but every one has been crushed, usually with collateral damage to good and honest folk. This would also reduce the charade of courts martial for relative minor infractions committed by junior ranks, whilst the millions lost through corruption go unaddressed.
The US Navy have probably gone a little too far the other way, but at least they have pushed such issues into the light.
(* yes I know there have been a few cases where a large group of more junior service personnel have escaped prosecution for prima facie offences due to potential reputational damage issues, but those decisions were looking up to the star chamber, rather than down.)
