For my nephew David, physical aggression, disrespect, and defiance started in kindergarten. He punched a teacher in the face on her first day back from maternity leave. Later, he aimed and threw a chair across the room. It took a principal and another teacher to physically remove him from the classroom. David needed help. That was obvious. At 6 years old, he was struggling with emotional and mental issues. He needed support and guidance. Instead, the system failed him. What happened next was typical.
