I thank you for letting me know we don't have tails, I had huge doubts about that in all my years of living. Now, you need your arms and legs to gather yourself and initiate the jump. By the time you're in the air, it's absolutely possible to have your arms and hands against your body; you don't need to develop a tail for that, I promise you can try it right now at home. Initiate a jump, and when you're in the air have your arms against your chest area. You will still be able to move your head in whatever direction the ball might be in the air. A handball, whether intentional or not, took away from a tap in opportunity. If you don't call it, then there's equal massive outrage from the other side (assuming the game remained tied or France lost) that a clear opportunity was taken away from a hand sticking out from the rest of his body. Utimately, the fault lies with FIFA leaving this huge grey area of intent instead of just penalizing without regard. It may be harsh, but I'd rather we don't have scenarios where we have to start interpreting the intent of players, and going through slow motion replays to make that kind of decision. It's up to defenders to manage this issue, and let's not leave it to a referee to make wild interpretations on a person's intent.
And on a side-note, I think it has been kind of ridiculous how France has had referees in their 1/4, 1/2, and final consistently each following game from the country they eliminated in Argentina and Uruguay. Surprised it wasn't a Belgian referee at the final. It's not even to say they would have an agenda against them (clearly, they didn't), but because now there is the added pressure for them that if, for example, Nestor Pitana didn't call this penalty then suddenly his integrity could be in check (whether that's true or not, you can't discount that it's something that could have crossed his mind at the time of making his decision).
