It is easier for clueless household members to get a hold of the earnings statement or unknowingly trade AMZN during blackout periods, so in some cases I can see how an honest mistake could happen.
However, this guy traded 1.5M 11 times during blackout periods ahead of earning statements. There is just no way to claim ignorance there. He had to have known that it's illegal.
I can't even begin to imagine the hubris or the stupidity. If they put Martha Stewart in prison for insider trading, they'll obviously put the husband of an Amazon employee without blinking. What was he thinking?
