If you consider the rate of suicide among returning veterans as an indication of undiagnosed mental illness/PTSD, then I think putting armed returning soldiers into a building full of loud, boisterous children is a very very very poor idea.If armed guards really are the solution maybe we should bring the boys home from Afghanistan and put a couple in each school. The school won't have to worry about the budget and adding another name to the payroll and both the students and the soldiers will be much less likely to be killed. I'm still not sure if I'm really sold on the armed guards idea. We'll see.
