Opinions are no longer opinions IF let's say that Ian received benefits (in either monetary or non-monetary forms). It then becomes an intended / calculated motive through implied action. This would be very easy to prove. This comes from a sibling of mine who happens to be an attorney specialized in Corporate Affairs (for one of the Big 4 actually). If I were Ian, I'd be careful... I see potential civil lawsuits (not criminal). If Ian is doing this simply to land a fat gig at GS let's say... then he's safe. But then I doubt that GS would hire a negative public figure like him. That's just asking for PR nightmare. Either way, I think he's screwed. Karma... just a matter of time.
