We had a tragic incident in our community in a local hardware store. A fifteen year old who had been subjected to merciless bullying and teasing snapped, grabbed an ax from the display and attacked one of the boys who had bullied him, splitting his face.

The boy is of Middle Eastern extraction and I don't know to what extent that was a factor in the teasing and bullying, but I suspect it played a part. Two of my cousins go to school with the kids in question and confirmed that the boy had been mercilessly teased and bullied at school for a long time. Now he is to be tried as an adult and faces a prison sentence.

I'm not saying it's okay to grab an ax and attack someone for teasing you, but I can understand how it happened.
