Regarding guns on campus, the Larimer County Sheriff, Jim Alderden writes:

. . .One of the real tragedies of the situation at Virginia Tech is that misguided administrators created a gun free zone where someone like this crazed individual could prey on other students, staff and faculty who were powerless to defend themselves. Their philosophy of keeping guns out of the hands of sane and law abiding citizens on campus potentially contributed to the tragic results. Locally, we are fortunate that at Colorado State University, the administrators have shown more common sense and recognize that a firearm in the hands of a law abiding citizens who frequent the campus is not a risk but could be a deterrent to violent criminal activity. While there are a number of students, staff and faculty at CSU who have Concealed Weapons Permits, admittedly, the chance of one of them being at right place at the right time to intervene is small, but compare this to the situation at Virginia Tech where there was no chance.

That last sentence echoes what I said after the incident:

Had VA Tech not been a “Gun Free Zone,” there is still no guarantee that there would have been an armed, law abiding student or professor at hand or able to prevent or to cut-short the murderous rampage but at least there would have been the chance of it. Instead — in the “Gun Free Zone” — the tragic victims had no chance at all.

Needless to say (needlessly,) not all law enforcement agrees with Sheriff Alderden. From a 9News TV (CO) article:

The University of Colorado at Boulder forbids concealed firearms on campus. CU Police Department Commander Brad Wiesley says switching that policy could decrease safety on campus.

“There’s no standard way to identify the good guys versus the bad guys in the middle of an active shooting situation. It tremendously complicates the response for officers responding,” said Wiesley.

Well, we certainly wouldn’t want to “complicate” anything by offering resistance. Officer Wiesley prefers the easy way to identify the good from the bad: The good guys are the ones laying dead on the floor because none of them were armed.
