If they can't find a gun, they'll use poison or explosives. Shaw feels the problem is that kids don't value human life. This is the result of taking God out of the schools. The students who were interviewed said they didn't feel safe in school. Most felt that school administrators did little other than suspend violators, who were soon back in school committing the same offenses.
Teachers are also afraid.
All across the country teachers have been assaulted, raped and murdered by students. I have interviewed high school teachers who illegally carry guns to school because they are afraid of their own students. They can't enforce discipline because the school boards and courts are so liberal. There isn't one answer. For the children, a good starting place might be an anger management course.
