My son (9 years old, 3 years in TKD) was recently physically punished in class. My son and other students (in full gear) were goofing off and messing around in class, sparring/kicking one another. My son kicked his friend in the stomach, making the other boy cry. I fully acknowledge that my son was wrong and that the instructor needed to address his actions - but... The instructor (a black belt) called my son to the front of the class, told him to stand with his arms in the air and then kicked him in the stomach. My son dropped to the ground and was gasping for air after getting the wind kicked out of him. The instructor then yelled at my son and told him to stand up. I wasn't there - but this was the story I got from both my son and another adult. I am bothered not only by an adult, black belt physically assaulting my child, but by the humiliation he also inflicted. Do I report this? I really think if this behavior happened to my child I am obligated to do something to protect other children from this 'master'. What do I do next? My son was not only physically hurt, but he was also humiliated as well. He loved TKD and was quite good, but now refuses to go back, even to another instructor.
