I really think there needs to be some protections from crap civil suits, but not complete and blanket immunity. First time I was sued by a defendant for a laundry list of torts, including loss of consortium, because I prosecuted him for a burglary where he was caught in the home, by the homeowner, who was coming home from deer hunting. NYep, held him on scene until the deputies arrived. Sovereign immunity saved me from having to spend a big chunk to defend myself. Second time, a family sued me after I prosecuted their 18 year old son for felony assault. His football scholarship offers dried up after he was a convicted violent felon. Again, sovereign immunity saved me. They were seeking $500,000 in lost educational expenses, and
I'm fine with allowing the suits to proceed if there's evidence of misconduct by a prosecutor, like concealing evidence. But I cannot imagine allowing the suits to proceed against a prosecutor because he got a proper conviction.
