I went to her HS school had a sit down with her teachers and the principal, after confirming there was an issue. Explained how our daughter had our permission to deal with any potential threat as she saw fit. Informed them as she was an honor student, IF they even considered suspending or expelling her after she fought back, i'd own them, the school and anything they ever looked at. Walked out with a firm assurance and hand shake from the Principal, VP and school board nothing would happen to our daughter.

We had a small issue in the jr hs , so i went to her meet the teachers gig. Her teacher it seemed had issues with females, including implying my wife was fabricating a story. Well about 5 min into him running his mouth, i asked him if he was lying, or saying, my wife and daughter were, as i stood up walked around the desk and sat on it looking at him about this close >< ....
Either you defend your child by any means necessary [ PROVIDING THEY ARE IN THE RIGHT] and not running some scam on you, OR you do not. IF they are in the right and you do nothing, you have no reason to be a parent and should be castrated.
