There’s a good documentary on firefighting in California on Netflix that came out a few years ago and the prison firefighting program was a good chunk of it. It looked like a great program for low to medium risk offenders.
I think it used to be more common to use prisoners as firefighters or labourers here, but I think the courts or some other good idea fairy seemed it was cruel for prisoners to do any kind of labour. I could be wrong though. I do remember prison farms and highway cleaning crews were a thing not long ago, but not anymore.
