I think the BA747 that continued to London was justified in his decision and also the AA767 was also justified in his decision. Both used all sources of information available to them and decided it was safe to continue. Both flights landed safely and their judgement was sound. Sometimes it is ok to land and refuel if you are not comfortable with landing fuel. To me that is good judgement. Also continuing a flight hearing a bang and fluttering briefly and then no problem doesn't require declaring an emergency, it happens sometimes. If I returned for an emergency landing every time I heard a thump or bang or flutter, I would have not completed a lot of my flights. Non of my continuations showed anything wrong. These guys did everything right and whoever wrote that letter to the press is an idiot.
