For instance, experience shows that a good many guns supposed to be unloaded go off and hurt people. The ordinarily intelligent and prudent member of the community [150] would foresee the possibility of danger from pointing a gun which he had not inspected into a crowd, and pulling the trigger, although it was said to be unloaded. Hence, it may very properly be held that a man who does such a thing does it at his peril, and that, if damage ensues, he is answerable for it. The co-ordinated acts necessary to point a gun and pull a trigger, and the intent and knowledge shown by the co-ordination of those acts, are all consistent with entire blamelessness. They threaten harm to no one without further facts. But the one additional circumstance of a man in the line and within range of the piece makes the conduct manifestly dangerous to any one who knows the fact. There is no longer any need to refer to the prudent man, or general experience. The facts have taught their lesson, and have generated a concrete and external rule of liability. He who snaps a cap upon a gun pointed in the direction of another person, known by him to be present, is answerable for the consequences. The question what a prudent man would do under given circumstances is then equivalent to the question what are the teachings of experience as to the dangerous character of this or that conduct under these or those circumstances; and as the teachings of experience are matters of fact, it is easy to see why the jury should be consulted with regard to them. They are, however, facts of a special and peculiar function. Their only bearing is on the question, what ought to have been done or omitted under the circumstances of the case, not on what was done. Their function is to suggest a rule of conduct.
