Original poster, you mean to say that that the US isn't like the films where a young guy "McLovin" trying to buy booze from an off-licence isn't taken on the adventure of a lifetime with two jovial but utterly useless policemen?
Most of us folk are in the UK and do not know the specifics of this, let alone what FINRA/FDIC means and whatnot.
So, you got accused of a dishonest crime and then were found to have not actually committed a dishonest crime but that will stop you getting the proper stuff for investment banking? Hardly seems fair.
Part of being a consultant is knowing when you're out of ones depth. You should seek legal advice.
A long time ago, Frio was caught doing something by a policeman (not a crime of dishonesty though) - I paid a lawyer who was qualified in such things to work through this with me after the fact. It's never held me back, apart from raising a few eyebrows (some of them bushy eyed style partner eyebrows, but not the one on this forum) when my best man decided to bring it up the details of that summer night in his speech at my wedding.
