The president and EIC at the time was Jenette Kahn. Bob Harras didn't become the editor in chief until well after Kahn left. She held that position between '89 and 2002, during that time Hal Jordan suddenly got old for no reason and then became a bad guy. After she left in 2002, less than 2 years later he was back. Clearly different people were running things at that point. So unless I'm missing something or getting my timeline wrong, Bob Harras had nothing to do with the Emerald Twilight fiasco.
