The Founding Fathers, writing in an age when single-shot muskets were all the rage, may not have known to what lengths their precious Second Amendment was destined to be stretched.
There has been a spate of legislation recently that enshrines the red-blooded American's right to bear an arm just about anywhere. As to whether it's wise to do so, the Founding Fathers sagely kept their own counsel.
One of the core arguments used by gun advocates is that when guns are regulated, only outlaws will carry guns. If everyone packs heat, then everyone is protected thanks to a kind of mutual assured destruction doctrine.
To take this to its logical conclusion, then, let's say (just as an example) that a female professor in Alabama goes berserk and starts shooting up her class. One of her students, thanks to permissive gun laws, is packing a rod and starts to shoot back. Another student walking down the hall hears the commotion, looks through the classroom door to witness a pitched gun battle underway between teacher and student, and draws his own cannon.
Who do you think he's going to shoot at first before asking questions later?
