Take a look at the article, Weaponizing Mozart. It's incredible the ingenuity put into thinking up devices like the Mosquito, techniques like shining bright halogen lights from helicopters, or forcing children in detention to listening to classical music, in order to influence or modify the children's behaviour.
Essentially it's putting all this time and effort into modifying children's behaviour without subjecting adults to the discomfort experienced in confronting and personally working with the children to change.
It's as if for some parents, teachers, and adults, they don't mind at all spending more money, time, and resources on the problem. Whatever it takes, so long as they don't have to actually face a child, build a relationship with the child, and work with the child constantly over time to internalize better and more effective behaviours.
