On top of that if there was evidence behind all indictments, then we would not need judges, only prosecutors. It is up to the court to decide if "there is evidence" or not.
Incorrect. Evidence is evidence. Anyone can judge evidence for validity. You could look up the evidence right now and judge it yourself. It only carries legal implications if a court prosecutes, but that does not mean the evidence does not exist or that a crime did not occur if a court did not prosecute.
