Who do you work for?

 for starters if you want to get information from these prisoners you can not be too nice to them because you'll never get any info out of them . you most likely would need to do some exercises with them such as sleep deprivation , or that water thing where you lay the person flat and have a towel over there head or you just simply play mind tricks with them. you don't have to go into such drastic measures and almost kill the person because what justice does that do and how does that help anyone one ?  If you keep messing with them emotionally your sure to get information some how. And if anyone mistreats theses prisoners then a short term response would be to make that person take a break for a couple of weeks and the long term response would be to fire them.
