the child wasnt forced under his own will to do the exercise. he felt he was up to the challenge and suffered injuries. its fucked up that the instructor got in trouble for making sure her course wasn't sub-standard to proper training. but then again she's a 3rd degree blackbelt instructor kicking the shit out of an 11 year old child. you gotta have some kind of common sense if you clearly have the advantage when it comes to the use of deadly force.
