 While Gilbert, May, List, Pettit, and others who concentrate on redeeming collective responsibility as an intellectual construct do so by defending the coherence of collective actions and group intentions, they do not go as far as to assert that all kinds of groups are capable of acting and intending collectively. Nor do they go as far as to assert that all kinds of groups can be understood as collectively responsible for bringing about harm. Instead, they assert that only particular kinds of groups are capable of acting and intending collectively and that only particular kinds of groups are capable of being collectively responsible for harm. What kinds of groups are these?
