re: "If we have an imperfect judicial system then we have NO choice but to err on the side of the potential innocent."
We DO have an imperfect judicial system. Indeed, what, in human experience, has ever been otherwise?
Thankfully, your conclusion is wrong.
Rare mistakes get made in trying people... but they're rare. Sometimes the system convicts an innocent person, but it's a risk that has to be taken because it is IMPERATIVE that we have a functioning judicial system - one that strives for fair treatment of the accused *AND* the victim.
You seem to have forgotten about the victim.
That's a glaring omission, so again I have to wonder. Do you have you have friends or family in jail, OCU?
If the justice system is flawed, the only fix I'd like to see would be the use of professional, trained jurors. And I honestly don't understand why any objective person would want it otherwise.
Your wish to "always" err on the side of a "potential innocent"? That would be lunacy. As we've discussed in recent days, eyewitness testimony is uncertain... confessions are uncertain... circumstantial evidence is uncertain...
The courts would be unable to convict anyone.
