RAI's new documentary: "The Hidden Massacres"

There is a new documentary out, made by one of Italy's RAI ( i believe it's RAI 24) channels called "The Hidden Massacres", in which allegedly the U.S. Army has been using chemical weapons in their attacks (specifically, white phosphorous) and they show how bodies are burnt while their clothes are still intact. I have not seen the documentary itself, but have seen interviews on it and debates about the 'legality' ( i can't believe this!) of using white phosphorous in battles where both so-called insurgents and civilians are its victim. This is very disturbing. The pictures are horrific.
