I don't think he was discussing gun laws. He is was discussing campus rules. Parents and students have choices as to what school to attend. I own several guns and I respect the second amendment. I have a daughter starting college next year and I am not sure how I would come down on this.
I will say that at a minimum, campus security should be well armed and well trained.
I haven't posted a comment on this horrifying event yet today but have been watching the news and reading this thread. Your comment is spot-on, IMO. Those who think that students should be armed are probably just upset right now; or at least I'd like to think that is their reasoning. We know that there are far too many unstable students, and other people, to start calling for students to all be armed. But those in charge of security certainly need to be well-armed.
What if this had been a suicide bomber instead of a gunmen? I bet the liberals if set up bommb free zones to stop that from being a problem, too.
The Constitution still applies to campus rules. Va Tech is a government school.
