flagrant fouls

A video recently posted on YouTube (see below) featured footage of a high school basketball team committing six fouls in which the videographer accuses the officials of miscalling the fouls.  Like many, he considered any hard foul resulting in the player falling to the court a flagrant foul.  Problem is that such contact is not automatically a flagrant foul; it could be an intentional foul, or it could be just a hard, but ordinary, personal foul.
