I was just wondering if putting a patrol by walls in outdoor areas will allow them to spot thrown contraband and reveal it. Otherwise that'd really suck

Currently fresh with a newish prison ive got mentally insane prisoners enabled as I like the challenge further down the line but im less than 10 days in and prisoners are going insane because the literacy demand isn’t being met I’ve got a library but I have no prisoners qualified to work there I have foundation programs but they take a while before someone’s qualified is there another way to decrease the literacy need if I put bookshelves in places will that help ?
