[just another ref]

I would actually be a lot more inclined to wait in this case. Was the original intent of the player to dribble? No. He went up to shoot and was prevented from doing so. His only option was a quick release and hope that a nearby teammate might bail him out. In the other example recently given, a player who has used his dribble obviously forgets, starts a move to the basket by pushing the ball straight to the floor, and the ball is then contacted by a defender. Is this a violation? It definitely is to me.
