That’s not really what I had in mind. What you described is like an alternate system.    What I would like to see is that the citizens, within the confines of the established system, could prosecute a crime. Investigators gather the evidence of the crime.  A “prosecutor” presents it to the judge and jury.  Not a new type of trial and punishment as you suggest. Just unrestricting those who are allowed to utilize the current legal system already in place.
