Yea.....gun nuts will jump all over that in some kind of vindication parade. What an extremely sad set of circumstances that push the need for armed guards on a school campus.
I believe that until we delve deep into our society to discover what causes, motivates these kids to go into a school and beginning shooting, killing that they will continue. What I want to know is what happened to our society that we require metal detectors and armed security guards in school. 20-30 years ago that wasn't the case. Here's a list of school shootings which doesn't include this latest one.

2014, October 24- Marysville Pilchuck High School shooting - (5 dead)
2013, June 7 - 2013 Santa Monica shooting - (6 dead)
2012, December 14- Sandy Hook Elementary School shootings - (28 deaths)

1998, May 21 - Thurston High School shooting - (4 deaths)
1998, March 24 - Mitchell Johnson and Andrew Golden - (5 deaths)
1991, 1 November - University of Iowa shooting - (6 deaths)
1976, 12 July - Fulerton, California - (7 deaths)
1970, 4 May - Kent State shootings (4 deaths)
1966, 12 November - Mesa, Arizona - (5 deaths)
1966, 1 August - University of Texas tower shooting - (17 deaths)
1940, May 6 - Pasadena - (5 deaths)
1893, December 13 - Charleston - (6 deaths)
1893, March 26 - Plain Dealing high school - (4 deaths)
1764, July 26 - Enoch Brown (10 deaths)
Notice that from 1764 through 1997 there were a total of nine. From 1998 through today 15 counting this recent one which is not on my list. Why the difference? Why so many over the last 20 years? I think if we find out the answers to those two questions we'll be on the way to solving school shootings. If we don't, whatever we do means nothing in the long run and they will continue.
