[BlogEntry] Death row inmate can't make a last good gesture?

Ok, somebody explain to me the logic of this decision. A Tennessee man scheduled for execution said that he did not want his final meal, and they should order a pizza and give it to a homeless person. It's unclear from the story whether he had a specific person in mind or was just saying it generically. The prison, however, won't do it. "The taxpayers don't give us permission to donate to charity," is the quote.

Lame. I always thought it had more to do with "last wish". He wants a pizza given to a homeless person. It's not like the prison itself is deciding to take his meal from him and give it to charity. It's what the guy wants. I don't understand the logic of that at all.
