Following on Joe Salazar’s comment that women should use whistles and call boxes rather than guns to fend off rapists, another Democratic Colorado state representative has offered even more alternatives. “There are other methods. There’s mace. What about a taser? The buddy system. Other methods at self-defense, judo or what have you,” said Paul Rosenthal, who represents the Denver area. Both Rosenthal and Salazar made their comments during debates over a proposed law to ban carrying concealed weapons on college campuses.
