It's a shame our tax dollars have to pay for the expenses of their incarceration.
Memphis had a penal farm when I was a child. The inmates raised crops for their meals, milked cows at the penal farm dairy for their milk and dairy products, and actually worked on the right of ways of highways picking up trash and cutting weeds with scythes.
Too bad we don't have this system in place today. Guess it wouldn't be "politically-correct", huh?
