We've heard how this unfortunate young man was picked on and bullied but it was also reported in his writings that he mentioned pedophelia. Any child who is abused or molested sexually is likely to have very long term effects and this is something that is extremely difficult for the child to come to terms with, even with counseling and often leading to severe depression, relationship and behavior problems and suicide. True, it's difficult to blame any one person or organization, but we all bear responsibility towards each other and I hope we can find a way to help and teach our children how to protect themselves from this ever happening again. My daughter (police lieutenant in Knoxville) suggests that if the students had been able to rush this guy, even if he got a shot or two off, they would not have been fatal and he could have been subdued. I taught at community college and more recently at university level and it's true that most windows don't open and most classrooms have only one door. When I taught at the community college, I always kept my cellphone and pepper spray with me. We really need to educate ourselves at every level to make things better and safer for our schools.
