I believe one of the major social functions of the legal system is to disseminate the law.
Random people don't read 100s of blogs a day. Random people don't track 100s of RSS feeds. Random people watch major historical events. I personally think it's good to subject randoms to social activities analogous to "code review."
It's not a matter of "one" versus "many". The problem is ALWAYS: Code for 0, 1, or ∞. What we're witnessing here is an Optimistic Aristocratic Approach, which chooses "many". In our society, "many" is too primitive and vague of a concept. I imagine this is why less complex cultures correlate with linguistic markings which top off at "many," or that it's simply highly probable.
In any event, Optimistic Aristocratic Approach (which assumes the lowest-common denominator in its decision procedure over its sample, not the "ignorant" or "non-technical"), to me, entails that the legal system is attempting to familiarize randoms with these problems, not only to set a precedent in the law, but to set a social template as to how these issues should be treated systematically in court rooms. It also gives us a gauge of how effective we are at communicating these problems to "laypeople." Of course, no society would want randoms if it could not assume randoms were competent; but no society would want randoms if it could not assume randoms were indeed random. "Randomness" is a feature of our legal system insofar as it is a fact of nature (mutation): we cannot respond to randomness blindly. Choosing our best, ignores randomness because it assumes we are knowers. Choosing one, like a previous poster has noted, involves a predictable historical trend in law. Choosing our WORST is insane. Choosing RANDOM is pragmatic, even if stupid. (I don't care to see this legal system or government last, but I believe all I've said can be taken without anarchistic sensibilities.)
We should all bear in mind, perhaps, that this legal system is largely going to analogize these issues to industrial-products and scenarios. I believe the thrust of "no, no! not the randoms!" is contained in the Internet Declaration of Independence. Do you remember?:
_Governments of the Industrial World, you weary giants of flesh and steel_, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather. [my emphasis]
I believe the point is not: "Don't trust commoners!" That's insipid and moronic. I believe that the general spirit is: "Don't trust commoners from the Industrial World to contribute meaningfully to our new set of values, whatever they may be!"
