 Peter French considers groups that are so organized to be especially appropriate sites of collective responsibility because of three salient features that they all share. The first is a series of organizational mechanisms through which courses of concerted action can be, though not necessarily are, chosen on a rational basis. The second is a set of enforced standards of conduct for individuals that are more stringent than those usually thought to apply in the larger community of individuals, standards that enable us to talk about both group conduct and group discipline. The third is a configuration of “defined roles by which individuals can exercise certain powers ” (French 1984, pp. 13–14) All three of these features, according to French, signal the existence of purposeful and controlled actions that are capable of rendering groups collectively responsible for harm.
