Sua’s point was that innocent people can be imprisoned without anyone doing anything wrong. In your examples of prosecutors who go forward with nonexistant cases, I would consider that to constitute misconduct. So I would agree with you that prosecutors should be deterred from proceeding with nonexistant cases, and that the falsely imprisoned person should be able to sue the people who commited the misconduct. But that doesn’t mean they should be held responsible when the evidence truly did point at someone who turned out to be innocent.
I do think that in many or most cases an innocent person who was imprisoned should get compensation, although not a huge amount. But what about cases where the imprisoned had commited other crimes at the same time as the crime which they currently in jail for, and in the process of commiting these crimes they created evidence which would later be used to convict them for a crime they did not commit? For example, if someone goes on a mugging spree, mugging 12 people in a month in a certain area, and then there is a murder in that same area and they are convicted even though they didn’t do it, because they created the evidence that would lead to them. In other words, it is really their fault they were convicted, and they caused the real murderer to get away. Should they be compensated?
Sua:
True. But remember that our legal system includes more than prosecutors and judges and juries. Even if all three of those acted as they should, it may be that the police did not try hard enough to find evidence, or that the police just decided who was guilty and stopped looking. After that, it doesn’t matter that the prosecutor and jury did their job perfectly. The system has already failed before the trial.
