I don't know if I ever recall seeing a CEO go to jail for practically anything, ever. I'm sure there are lots of examples, but at this point in my life I have kind of derived a rule of thumb of "if you want to commit a crime, just disguise it as a legitimate business" based off seeing so many times where CEOs get off scott free .
FWIW, Joseph Nacchio (the CEO of Qwest Communications) went to jail for like a decade for refusing to help the NSA violate FISA circa 2001.
