What is the best way to deal with a parent who never thinks their child does anything wrong? They think their child does not lie and will never intentionally hurt or make fun of someone else. The Principal has even brought this up to the attention of the parent. The parent is quick to blame the actions on other students instead of their child.
I completely agree
I see myself using your solution when dealing with parents like the ones in the original post.
I am not sure if video taping would be the best solution. It might make the situation worse by creating a scene and "shaming" the student in front of the rest of the class.
