There are no crimes in Hawaii other than those established by the legislature.  HRS 701-102.  However strongly people disagree on the subject being discussed here, no one would want to prosecute someone who attempts suicide and fails.  Clearly, even you would agree that other remedies are more appropriate/necessary.  Just as clearly, the legislature would not pass such a bill and no governor, not even Linda Lingle, would let it become  law.

So let's stop speculating about the number of angels that might be able to dance on the head of a pin, or whether lightning might strike a unicyclist riding atop a moving bus.  Good policy decision making requires keeping it real.
