If Mr. Liang is a P.Eng., I hope he loses his license. There should be a bunch of Engineers losing their licenses.
There should be some executives losing their jobs and freedom, if this guy is pleading guilty to several felonies. He wasn't acting on his own initiative.
I suspect it'll be the same, though at least the CEO resigned over this. I'm sure Winterkorn remains a multimillionaire, and will continue to enjoy his freedom and lack of criminal record.
