The amazing thing to me is and yet at the time nobody actually did anything. That is why he got away with it for so long, he could repeat the same thing that already got him convicted once with such impunity because everybody was willing to look away when confronted with the specifics.

Each and every one of those people underneath Ito who suspected something might be up had the opportunity to do something about it, including going to the board, and given their suspicions they should have. And yet, nobody did.
