Collateral damage with a baseball bat or hammer is a lot harder to produce than with a firearm.
Many would simply jump in and try to save the drowning person. No thoughts, just jump right on in to the body of water. An educated (or intelligent) person would evaluate the situation and find a way to save the drowning person and himself in the process. Getting a drowning person out of a body of water is not always the simplest task. There are lots of variables to consider. Jumping in blindly without taking a second to look around could very easily yield to both parties drowning, even if the second one was just trying to help.
Yes, you could just jump in and hope for the best, but taking a second or two and evaluating would likely make a big difference. I argue the same holds true for CHL holders. Someone with moderate training would be much more able to save themselves and others (if they so choose). Low to no training could very easily yield to unnecessary collateral damage.

You realize that we (as Americans), can bring as many empty 5 gallon gasoline cans to a gas station and just fill them up as long as our credit card works or we have the cash, without adult supervision, training, or a special permit? We can do that at over 10 million gas stations nationwide. As many people can as the country has, and as many times a day as they want. You could literally have 200 gallons of gasoline in the back of your truck and drive almost anywhere in the country (including gun free zones), and in one instant/accident/malicious attack, level nearly a city block. Want to talk about lethal collateral damage? Take a 5 gallon jug of gasoline and light it in your backyard.
But again, no permit, no special training, no diapers needed. You can do that with lethal pesticides, herbicides, and a host of other combustibles as well.
I view the likelihood of most gun owners (and stats back it up), to cause about as much collateral damage in their everyday association with a firearm as a hyperactive vampire in charge of a bloodmobile.
Theoretical incidents of death and destruction from gun owners allowed to carry in colleges are just that; theoretical. The incidents of campus gun violence are minuscule. It is only the added hysteria and phony outrage that makes them so massively disastrous and seemingly prevalent.
