A question of ethics
On July 1, 1993, Gian Luigi Ferri entered the offices of a law firm against which he had a grudge. Using two semiautomatic assault weapons (TEC-9 and TEC-DC9) manufactured and distributed by Navegar, Inc, he killed eight persons and wounded six others before killing himself. The survivors and the families of some of those who had died sued Navegar, based in part on negligence. They claimed that Navegar had a duty not to create risks to the public beyond those inherent in the lawful use of firearms. They offered evidence that Navegar knew or should have known that the assault guns had "no legitimate sporting or self-defense purpose" and that the guns were "particularly well adapted to military-style assault on large numbers of people."

The appellate court reversed, ruling that the case should go to trial. The court stated that "the likelihood that a third person would make use of the TEC-DC9 in the kind of criminal rampage Ferri perpetrated is precisely the hazard that would support a determination that Navegar's conduct was negligent." Navegar appealed the decision to the California Supreme Court. In view of these facts, consider the following questions.
