First, I was appalled that the girl and her father used the horrific and deadly stabbing attack as a soapbox for her situation. And because of their complete lack of consideration of the actual victims in this case, I take her story with a very large grain of salt.
Second, physical assault is illegal. If a parent is not happy with the school's discipline after their child has been attacked, they should call the cops. At least that's the case in my area, not sure if that varies around the country.
Lastly, the assailant was not physically attacked. If anything, someone teased him on Facebook. Solution? Unfriend the person who is annoying you. Taking a knife to school and attacking innocent people is not about the school not doing enough for "fragile" child egos. It's about a young person who is vicious and homicidal. JMO, OMO, MOO.
JMO, I think there was probably a lot of denial going on by the assailant's parents & school officials. Again, JMO, a perfectly normal child doesn't suddenly wake up one morning & decide to maim or kill as many people as possible.
