Virginia Tech Tragedy

Thirty-two people killed at Virginia Tech University and a Korean student is identified as the lone gunman who took his own life after the killing spree yesterday.
Here are a few things to think about.
First, it all started around 7:15 a.m. when the man confronted his ex-girlfriend. When a dorm advisor tried to stop the confrontation, the gunman killed the advisor and his ex-girlfriend.
Police investigated and found a girl and the advisor shot dead and presumed it was a murder suicide. Perhaps a bit of Barney Fyffe here, but did anyone think of attempting to look for a weapon that would have been used in this event?
So, while the university notified students and others there was a shooting incident, the gunman went to another part of the university and too 30 more lives.
Ironically, the Virginia Legislature refused to approve legislation which would have allowed Tech students to carry concealed weapons on campus.
Here's an idea, instead of building a fence around a university, passing tougher anti-gun legislation and preventing conceal carry of gun legislation, why not require university professors to carry concealed weapons?
You can't hire enough security guards or build enough fences and besides, if you want to have a college campus, have a college campus, not a fenced in school prison.
And remember, every college and university may, may use this as a way to request an increase in their budgets to hire more security.
Here's the problem, sometimes bad people do bad things, and for those familiar with mental health issues, many other incidents are referenced with the concern that, "the killer had a history of mental illness."
Now reports show the killer left a disturbing note. It won't be long now.
