Yes, it would typically be a long process because of what is involved, the hours of volunteering, the hours for research, speaking to those involved again after so many years, etc. I just watched episode 8 and it talks about legal immunity for prosecutors and imo this one thing is the main thing that should be adjusted for all states. Anything that deals with the government and the legal system as it is, is a long process, but no one is held accountable when they do things wrong on purpose. It creates a no-one-can-touch-me mentality since they know they can never get in trouble.
I thought the episodes would get better by getting tamer, but they appear to get worse. It makes you think how many were on death row, who have been killed, that were actually innocent. I wonder if there is going to be another season. Sometimes I do have to take breaks just because the material is so heavy and it makes you very angry that here we are in 2020 and the system still is whacked. I do like how the perspectives are all explained from the attorneys', to the jurors, to the defendants, to the families, etc. It's interesting to find that the confessionals are well rounded.
