The most he’ll get is a slap on the wrist.
Nahh, a slap on his arse. Nekkid.
His activities were not accomplished in a vacuum and certainly took place over some duration, so you KNOW there are people with as much (possibly, more) culpability. It's imperative to expose his DIRECT affiliation with all these others, who enabled his crimes and who of course, did so for personal GAIN.
If even by association or if they only enabled him by failing to blow the whistle, once their brand and their careers are ‘diminished’, then the house of cards can come down!
