Fort Leavenworth used inmates from the stockade to do lawn work and other chores around the post.
What’s the big deal?
They were glad to get out and did a lot of things cheep. It wasn’t `The Shawshank Redemption’.
Whenever I see a prison work gang out policing the roadside litter, I think, if I were ever "inside", I'd take that job if it were offered.
Beats sitting in the common room with the TV. THAT qualifies as cruel (though not unusual) punishment.
