Yes, Sam, we are very different and the feeling is mutual.
Why should it bother you that someone who would kill, or be responsible for ordering so many deaths, might be executed? Some actions warrant more severe punishments than others. We're not talking lifting a few candybars or boosting a car. Should I take from this that you believe all the Nazis who were hanged after Nuremberg should have instead been left to rot in Spandau prison?
I want to say "Duh!" w/regard to your point about inflamed passions b/c we're talking about the middle east. Regardless of SH's final sentence, there will be problems. The problems won't end b/c SH is spared. If he is, it will be to a prison in Iraq, not the US, and that will likely become a lightening rod for increased attacks by sunnis looking to break him out of the klink. If he's spared, it's just as likely that the shia and kurds will be verrry POed and would stir up trouble. SH's fate is a Catch-22. So, as far as I'm concerned, there's no reason not to execute him.
As I wasn't addressing the question of deterence w/regard to others, your point is irrelevant. Life in prison is no guarantee he won't get out (ie escape) or that he couldn't cause problems from within jail.
As to the whole money thing, it's not a question of whether we've got enough money, but rather if he's worth the expenditure of funds that couldn't be put to better use elsewhere. The DoD might have the cash, but it'd be better spent on ammo and spare parts.
