Not to go off on a tangent, but this issue kind of points out something that I think a lot of people don't consider. There is a perception among many, subconscious most of the time, that equates the law with morality. That was more true in times past than it is now. Just because the law says something illegal, doesn't mean it's immoral and just because the law says something is legal doesn't make it moral by any stretch of the imagination.
I like what Zon has said more or less in this vein. I would argue that laws were created to rein in on those who lack some of the finer aspects of morality. Theivery comes to mind.
