I agree that it’s crucial to teach children about tolerance at an early age. But that’s not enough to just teach them anger management. You have to teach them why they should manage their anger in the first place. Learning to cooperate, do good deeds, understand different viewpoint… Once they learn that there are better ways than violence, they will be less inclined to resort to violence. But then we have people with mental conditions that make them unable to understand human’s feeling. Those are the people that will defy the system and make the headlines. So the program will surely help a lot of people, but not all.
