This is what I imagined happening leading up to this picture: This guy - let's call him Phil - can't see a thing without his glasses. One day while waiting to get on the bus for a class trip, his glasses got dirty. Still blinded, he got on the bus and sat down. This picture is the exact moment after he cleaned his glasses and put them back on. "I've made a terrible mistake."
Can you imagine how terrified you'd be sitting among a bunch of convicted criminals? Who knows, maybe some of these guys are nice guys and all, but you just don't know. At any point they could snap, especially if they have a life sentence. You know what a life sentence in prison means? It means kill all the people in prison that you want.
