When news came yesterday morning that State Representative Peter Pettalia had died in a motorcycle crash, the first question everybody I knew asked was: Was he wearing a helmet? Pettalia was a key player in the successful drive four years ago to repeal the law requiring motorcyclists to wear helmets. Turns out that he was wearing a helmet at the time of the tragedy, which evidently was not his fault. The brutal fact is that if you are going to collide with a heavy, vast-moving vehicle, a motorcycle, unlike a car, offers almost no protection.
