Martigan,
First off, excellent "Willow" reference!
Second, you're absolutely right. There DOES exist a pretty good argument for elimination of juries. This is a debate that is usually engaged in by most first-year Civil Procedure classes in law school. (And, I'm sure there's a thread about it somewhere on TFL.)
In old-fashioned English Common Law, there were very few trials by a jury of peers. It was believed that issues of legal justice were too complicated to be understood by the common folk. (Remember, the VAST majority of English commoners at the time were illiterate.) The English justified the elimination of layperson involvement in the legal system by simply stating, "Best leave this to the legal experts." As a result, English Common Law was VERY difficult to understand. Most of the terms were kept in Latin. There were very few hard-line definitions; everything was open to debate and argument. And, in the end, the question of guilt or innocence really was left to the judge.
The problem with this, as Jefferson and Adams pointed out, is that judges in England typically sat alone. In other words, there was only one judge per trial. A single person can be corrupted. He can be biased. He can be bought. Or even worse, he just might be completely unenthusiastic and disinterested in the particular facts of any particular case, such that he will not even listen to what the parties have to say. (Judge Judy would make a GREAT English Common Law judge!)
Juries consist of multiple people. And, although a jury can be tampered with, it is MUCH more difficult to influence the outcome of an ENTIRE jury than it is to influence a SINGLE judge. Jefferson and Adams thought that a "jury of peers" would be a more secure way to insure administration of real justice. And, I agree with them.
But, I feel that the jury system has moved quite far away from Jefferson's intentions. What Jefferson and Adams meant by "a jury of peers" was that they wanted to be judged by all the OTHER rich, white, slave-owning, aristocratic, tax-dodging, male landowners in the Colonies. In their day, if you wanted to be on a jury, you had to be a landowner. Only men could own land. Land was EXPENSIVE. So, this was a way of ensuring that everyone who served on a jury was well-off, educated, in a word: LITERATE!
Now, by no means do I claim that only landowners should serve on a jury. But, I do feel that we would all be served well by the institution of some minimum level of intelligence and/or education on the part of our jurors. In any case, the current system of letting anyone who posesses a scintilla of education be recused from jury service for "professional reasons" is quite flawed. The doctors and lawyers are the ones we MOST NEED to be serving on juries.
