I don't really care , do you?
A child was murdered at a school track meet. Maybe you don't care.
It's not like he was in some back alley too. Of all the places to get in a fight at, that's probably one of the safest environments you could ask to be in, even if someone started it and was physically assaulting you. There are plenty of adults there who would intervene. There is really no justification for it. I don't understand how anyone can support the killer. As a parent, you shouldn't even have to worry about that happening to your child at a school sporting event.
