I totally agree woth everything that is said her and for those that dont know i teach high school shop class and have mentioned several times all teachers need armed in case something like this happened. In my defense I say you never hear about someone goin in a prison, police station, or gun shop and open fire. Hell no you dont because they know their ass will get shot back at. All robbers and killers like this always hide or do it to the ones they know cant defend theirself, such as elderly. Big pansies if you ask me to do this then kill theirself because not man enough to face what they have done.
Then there is the argument if he would not have killed himself his lawyer would claim he is got mental problems. You damn rite he does but you cant tell me he doesnt know rite from wrong. I have seen students that have to have help just to walk down the hall 2 doors down because they get lost but they know its wrong to steal a pencil. In gona end there because I could go on all day.
