Thanksgiving Turkey

The local newspaper had a story about the inmates in the county jail would not be receiving turkey dinners on Thanksgiving due to budget cuts. It seemed to state that people would be outraged at this. I for one applaud the sheriff for not giving them the dinner that would cost about $2,000. They have already laid off 20 employees. And since when did being incarcerated mean that you get to enjoy turkey dinner. I thought the point of jail was to deprive people of things so they wouldn't commit crimes. Did I miss something in civics class?
