Oppose the law because it is a clear violation of privacy rights.
Certainly Jennifer is now very glad her rights to privacy have been respected.
Unless you can prove otherwise, I see no reason to assume that Jennifer did anything other than make personal choices that she felt were proper decisions in her desire to live a fulfilling and enjoyable life. While I understand the hurt her family may feel, the notion that we could dictate happiness is ridiculous.
...and these personal choices turned out to kill her. We all believe in personal authonomy and free choice, but when someone is endangering his own life, it's the government's duty to avoid that.
How so? Maybe it would make sense to proscribe reckless risktaking if the person in question had a legal responsibility to some other person that could not be fulfilled in the event of that person's death, but it seems highly intrusive to decide that people must be barred from endangering their lives, not to mention a principle that is not really observed in American law, or any law that I know of. If it were, then mountain climbing & skydiving would have to be outlawed since those are both obvious examples of endangering one's own life.
