Rules of statutory construction, rules of evidence, and rules of equity exist to protect against absurd results. Results that seem absurd in newspaper articles most of the time are not absurd in actuality. The purpose of legal fact-finding is to resolve disputes in a civilized manner. As Justice Brandeis eloquently stated long ago, it is the alternative of the gun battle in the street. There is no magic in science.
Jurisprudence generally serves the interest of ordered liberty.
There are more legal controversies than scientific controversies because in order to expeditiously ferret out temporal truth in a dispute, as courts and juries must, the adversary system is essential. Society has lots of problems, the most serious of which tend to wind up in court. By their nature these kinds of problems in many instances are not capable of satisfying resolution, or noncontroversial resolution. It is sometimes tempting to mischaracterize society's problems as legal problems. This is not to say the legal system is perfect.
