we need more data to decide upon this guard's fitness for another job ..... did he call for back up ? Was he denied a bullet proof vest ?? Was his job description or on site training have any conflicting rules of engagement ??? Did he have prior knowledge of this former student/remember him from previous attendance ???? Was he paid enough for affording a very large life insurance policy to cover his family or beneficiaries and should it be "combat pay ? " ????? Was there "cover" or a safe path to sneak up on this SAVAGE SICKO ?????? Did the guard have a clear shot at the perpetrator or was he out of effective range down a long hallway where bullets can ricochet off walls in unpredictable directions ???????????

I wonder if he is a card carrying NRA MEMBER?

I imagine some of the guards will just go and hide and some will do the job properly get the insane person. We need to catch those people before they start killing...
