The principal viewed the bus video, his statement: What I saw on the video was not an assault but not a backhand push. She should not have put her hands on him. She did apologize to him.
She was talking about him to a mutual friend sitting across the way and when he interjected, she turned and whacked him. My daughter and others sitting around them witnessed it and said it was unprovoked and not meriting a hit.

For future reference: the school will usually minimalize these situations. If you want a potentially criminal act to be taken seriously, report it to the police, not just the principal. The school does not have the ability to do much other than suspend students...
Reporting the incident to the school is fine, but if you were to take something to small claims, a police report would be helpful.
