My nephew was attacked at school in front of security. He had his jaw broken and missed 6 weeks of school. The kid that started the fight and broke his jaw missed one day of school. The school refused to prosecute him even with a adult eye witness who was there for security.
Then the video that they said they had of the fight was somehow lost.
On the other hand my daughter who we homeschooled started college when she was 17. She now has to bachelor degrees. The two bachelor degrees biochemistry/cell and molecular biology and anthropology.
I did not want her in public school to pick up the bad habits from other students. My two kids were so well behaved that when the IRS did a audit at my house the auditor was shocked and commented how well behaved they were. As compared to the kid who broke my nephews jaw.
I finally got the principal to do his job after the threat of a lawsuit, and the boy apologized, they even became friends.
Because of learning of the incompetent teaching, we homeschooled not long after that.
