How many really good lawyers would risk taking a job as a prosecutor when they could make so much more in private practice if in the process of discharging their prosecutorial duties they were going to get sued for every case. Without that immunity, multiple lawsuits at the end of the prosecution of crimes would be inevitable. Local governments would have to pay the bill for defense, but verdicts might be against the prosecutor personally. They won't risk their family livelihoods for public service. A change in the law here could really bankrupt local governments and then other services would go away like road maintenance, garbage collection, zoning and haz mat enforcement and the social services for the protection of children, vulnerable elderly persons and the developmentally disabled.
