The following video shows a Korean teacher hitting his students with a Kendo bamboo stick. Kendo is the Japanese martial art of fencing. When practicing Kendo, people wear protective gear that covers the upper body, including the face and head, but the students being punished here have no such protection.
The students were beaten for missing a makeup class. (See HERE.) A representative of the school said the school was sorry about the incident. The representative also said a personnel meeting was held, and the teacher who beat the students was given a warning and was forced to apoligize to the students he beat and to the rest of the class.
A warning and apology? I say give the two students the cane and let them beat him for a while, and then the school should fire his sadistic ass.
