A New Approach to the Judicial System

What if we let the Judge decide innocence and guilt, and let the jury decide on punishment?
Judges understand reasonable doubt, while jurors often act on emotion and intuition. Perhaps there should be a panel of judges, who, upon hearing the evidence, decide if the plaintiffs proved their case of not.
The jurors, who represent the community at large, can decide the severity of the punishment. There will be parameters, of coarse, so car thieves don't get the death penalty.
The problem with the current system is that it relies too much on the jurors ability to understand legalese. Lawyers aren't trying to prove their case, as much as they're trying to manipulate perception.
Perhaps it's time to try something different.
