As soon as he realized he was wrong he admitted it in "public". He didn't try and milk it for some nuisance value settlement. Initially he attempted to get out in front of this by repeating what his client told him. The longer a case lingers the less value it has and making it public helps to weed out witnesses. etc. Once a client tells you something that you discover isn't true you have a duty to advise the client you cannot represent him unless the "untruth" is on a minor detail. This was the entire potential case. He did what he is supposed to do. It is certainly not unusual for an attorney to take a case only to find out there is no case. Happens every day. He acted the way he should of. Nevertheless, it does give ammunition for those who, for a myriad of reasons, don't care for lawyers.
