I’m somewhat skeptical that this belief of yours is actually true. Certainly, there are plenty of instances of gun violence in locations such as military bases, where the shooter must have been aware that there would be other armed people around.

Kimstu, your skepticism is fine - that’s why we’re all on this site after all.
I would consider it common knowledge that criminals (especially of the premeditated sort) tend to prey upon people they perceive as weaker, whether through size, distraction/surprise, use of weapons, etc… This is a basic principle of natural predation as well.
Most of the citable articles that cover this kind of criminal psychology online require subscriptions - one of them is the rather provocatively titled “More Guns, Less Crime” by John Lott, but there are other better ones such as this about criminal psychology couched in terms of evolution:
A GENERAL PARADIGM FOR UNDERSTANDING CRIMINAL BEHAVIOR: EXTENDING EVOLUTIONARY ECOLOGICAL THEORY
Certainly the notion that victims may be able to fight back effectively is not a panacea for preventing killing sprees, only a deterrent. Thus such counterexamples as the ones you provided will always exist - there presumably will, given enough time, always be someone crazy or enraged enough to commit them. A few others have pointed out that your cites are closer to straight out murders, but that’s not important.
What is central is the idea that the semi-rational killers dominate over the the ones completely enraged to the point of madness, or deluded into thinking themselves invulnerable. For the latter category, the victims can still fight back of course, but it’s better that the shootings not occur at all.
This aspect isn’t really citable, the number of shooting sprees that could have occured, but did not, can not be known. I think the asymmetric choices of places for them bears out the principle - the number of shootings in schools can be partially attributed to youngsters and the stresses of schools, but there are significant examples like Dunblane, and the Amish schoolhouse where the killer is a adult - well above school age. Why pick the school vs other places?
Given the notion that criminals will generally go after weaker victims, it seems highly likely that the fact that no one there can fight back is a basic consideration for the murdering loons. I grant that this is speculative and unknowable without a mind reading ray, but good old Occam and basic criminal psychology seem to dovetail pretty well together.
I suspect the CCW aspect is more important than is usually realized here - cops with guns on their hips walking around are fine, but are very conspicuous and can be planned for by a nogoodnik bent on a rampage. The possibility of random armed citizens is a more difficult unknown, and so the bad guy picks a place where the risk is minimizable, if possible.
I agree with Hentor - a death is a death for the most part and so for matters of policy discussion the balance between presumably fewer killing sprees vs presumably more “accidents/settling of scores” should be addressed.
This is why I mentioned some more practical methods of resolving the problem of violence in schools in my earlier post, all this stuff seems to come from weak social skills and chemical imbalances first and foremost. At best relaxed CCW in schools and other places would be a weak solution that doesn’t address the fundamental problem of violence and dangerously unstable individuals. But similarly as for society-at-large, it would appear to be a net positive over the converse.
