I see a moment of comedy - a big fat buy who hasn't a prayer of being able to jump far enough to keep his feet dry. And might slip and fall on his but in the puddle.
HCB definitely produced many wonderful photographs. The fear and panic of the Chinese lined up outside the bank gives me shivers. What is wrong with knowing that you aren't the greatest printer in the world?
BUT There are an almost infinite number of decisive moments every day. Taking credit for finding "the" decisive moment is mainly a matter of self-promotion. Part of his genius was his ability to see possibilities, put himself into position to capture "a" decisive moment, click like crazy, and claim after the fact that he had found "the" decisive moment. He also thrust himself into important events where the decisive moments would have power. Heck, even St Ansel bought it and praised him.
