As a postscript to my last (below), apparently Texas is no longer letting prisoners choose their last meal before they're executed. It seems that some of them have been making exorbitant demands (how dare they?), and in any case (says Texas) they don't deserve a special meal. They're criminals. Let them eat the same as the other prisoners.
It's good to know that compassion and humanity are still alive and well in Texas, even if 400+ prisoners (since the 1980s) are not.
