Up to 20 years? Damn, that's incredible... And to think that in the US, voluntary manslaughter incarceration is "for a period of no more than 15 years".
Someone could have died and they'd have got a lower maximum sentence. LOL
Ah, the US... gotta love their priorities...
It's supposed to be a deterrent and this was a conspiracy to defraud through the mail system which is a federal crime.
Sure it seems lopsided, but these people were also Chinese Nationals and you can probably guess the Federal Prosecutors were sending a message to other foreign conspirators to not defraud US companies.
