Too soon?

In all seriousness here: when I heard about the Virginia Tech massacre, passing by TVs in the hallway of the building where I work, one thought rang out clear in my head, and kept nagging at me for days afterward:
“At least the National Guard wasn’t involved.”

Kent State University, Ohio. May 4, 1970.
What happened at Virginia Tech was a horrible tragedy, and it calls into question issues ranging from the state of mental health care in this country to the ridiculous availability of guns to the incompetence and lack of preparation of college campus security in general. But at least Virginia Tech was just the result of one nutjob with a messiah complex, and not a military action on unarmed civilians on a college campus.
