The liability calculations are being done from the perspective of liberalism. A conversation I had with a chief of campus police yielded a different tone on the liability issue: CYA and PR. They know full well they can't have any means whatsoever to fully detect and stop a loony from repeating these disasters, so the only people they can tell anything about whatsoever are the people who are licensed. They have to feel like they're screening at some level, so that's the level they can do it. Where I was, the sheriff's department issuing the CCW had to inform the school that you were getting it and the school had an agreement with the department that the chief of campus police had to give them a letter of approval--basically that he knew you had the license and had personally told you not to carry there and that you'd be in trouble if you did. Basically they'd have information on how many people had a permit and who, so they could officially say to administration and parents that they were doing something to monitor people on campus who might have a firearm. That's it. Nothing more. Just purely to say to the parents who might be worried for their kids and say "Oh my god, you have no idea about who might be carrying a gun there!" They can say they have something more than nothing, and they can tell the administration "Hey, we have a tight lid on it. We know exactly who has a gun and we can keep anyone we deem necessary from being able to. We have only allowed _____ permits."
That's straight from the source.
