I'm a second grade teacher. I have a boy who lies constantly, about anything. He was on camera, watching the footage of himself punching a student in the face and he crossed his arms and said, "If I didn't do it then I didn't do it." The worst part is him mom believes every word he says and attacks the school for making him accountable for his actions. He's going to do something as an adult and go to jail. When they pull him away I know he's going to be yelling, "If I didn't do it I didn't do it!"
