It might be fallout from his old heroin habit.
Are you sure that's the Kennedy with the heroin? There were a few.
Yes, all those drugs eat up the brain cells and depending on how many you have to waste... My guess is this guy was not overly endowed to begin with and once he got straight (assuming that he did) he could use the ones he destroyed to function someplace in the normal range.
Does anybody know if there is any law in N.Y. in regard to a felon running for and holding the highest law enforcement position? I know he's a Kennedy and that probably gives him rights that peons don't have, but it seems odd to me that a drug felon could be elected A.G.
