"No great idea in its beginning can ever be within the law. How can it be within the law? The law is stationary. The law is fixed. The law is a chariot wheel which binds us all regardless of conditions or place or time." - Emma Goldman (1869 - 1940)
"Codes of conduct redefine
As justice turns to legal crime
These monsters masked by human features
Are by far the blindest creatures."
-Skyclad - The Ilk of Human Blindness (1993)
Law is a curious thing, created by those above to keep order and civility in our society. But rarely does that hold water for long. Dirty creatures will make their way into power and create laws that weaken their opposition and furthers their own goals. That's the reason I do not follow law but a flexible moral code, "Don't be a dick" is the headline.
"What role did authority or government play in human endeavor for betterment, in invention and discovery? None whatever, or at least none that was helpful. It has always been the individual that has accomplished every miracle in that sphere, usually in spite of the prohibition, persecution and interference by authority, human and divine." Emma Goldman (1869 - 1940)
It is my belief that authority is there to feed itself and keep itself alive as long as possible like any living creature. Law enforces its survival by keeping its food contempt and satisfied. Change and progress is the killer of this creature because often it makes it clear that we don't need the creature, or at least not all of it. We need only look at Galileo and his battle with the standing authority of that time, the Catholic church, to see that governing agencies have no interest in advancing the human race, just keep it content with what they've got. The law did not want to find out more then they already "knew". And they keep the tradition going by ignoring global warming, blaming condoms for aids in Africa, claiming that cannabis is more harmful than cigarettes. Who here would sit silently obedient if the crackpots of the southern states would make it law that creationism be taught alongside evolution?
Like the ten commandments, law enforcement was not the first to say that killing is kind of a bad thing, we knew that already. Being a dick is not something that society in general finds acceptable, we figured that out ourselves. There are of course dicks here and there that do dickish things just because, and they should be treated like dicks, public humiliation is my preferred method of undicking them. I could go on about how the imprisonment system fails miserably but that's not the discussion here.
TL;DR: Point is, law is either redundant (stating the painfully obvious to any rational being), idiotic (stating something downright ridiculous that no man would be able to follow or should not have to follow), or cruel (stating something hateful towards a group or groups of some kind of people).
