It is long enough to destroy his life. What matters if he gets out at 70 or 80 if he gets out at 60?
Hardly. Milken was sentenced to 10 and served 2. SBF will serve 7, at which point he'll still be under 40.
He won't be out for ~two decades.
Milken was released because Trump pardoned him, which I don't think says anything about how sentencing guidelines do or should work.
He was released after a sentence reduction for cooperation with prosecutors against others decades before the pardon. Both the release and pardon occurred, but the latter was not the reason for the former.
TIL, thank you! That makes me feel much better at what initially seemed like a slap on the wrist.
