So the Government controls what Criminal Charges are to be brought against the Citizen.
The Government then controls what Evidence May be introduced in said Trial.
The Government controls and decides WHO can be a witness and what they can say, and who may Represent the defendant and their speech also.
The government then tells the JURY What their law means and that they cannot deviate regardless of the circumstance, Which is an Out and Out LIE, Jury Nullification has ALWAYS been the Safeguard the people had against Tyranny and has been used to nullify bad law throughout history
Why do we have trials anyway??
The same reason that the TX NG is being deployed
to the border: appearance.
You forgot to add in overcharging, then plea bargaining.
