Agreed. Have one judge overseeing the court proceedings as we do now, and have three or five other judges replacing the jury. They'd be far more likely to understand the evidence presented on both sides, and far less likely to let someone off "because they seem innocent".We shouldn't rely on individuals for anything. Checks and Balance are in place for a reason.
The fact is that the average person can't be trusted with such matters. People are dumb, and can easily be biased and prejudiced towards the defendant, or in favour of them.
For example, let's say a man is stabbed to death in rural Alabama. A few days later, Mr. Mohhamed Hussein is brought into court and sworn in on a copy of the Koran. Go on, just try and tell me that a bunch of hicks from rural Alabama are going to let that guy off, even if he's innocent.
On another note, I find it telling that not one person has stepped up to defend the jury system. I think we're all in agreement that it sucks.
