On the space issue, that holds no ground to me and I have driven throughout most of this country and trust me, we are not hurting for space and over populated yet.
Not sure exactly were you've "driven throughout" but I have family that work in numerous jails/prisons that can definently tell you different.
Can you give some hard facts as to how many innocent men have actually be executed?
I know you'll probably say "one is enough" but i'd like to get some fact on that.
