They forfeit their rights to be treated as humans when they murder or attempt to murder innocents.
That shoe bomber ought to be, POOF! GONE!!! He would have murdered hundreds of people on that plane....but for the brave actions of ACTUAL HUMANS on the plane.
I am sure that some folks here on FR would like to go to the place he is jailed with a tray of yummy cookies for him....and, perhaps a box of candy with hearts and flowers for the "poor sad, much maligned" jihad TERRORIST!
No, it isn't proper to go around frothing and the mouth and wishing you could drink the blood of your enemies. Especially when you see "the enemy" as anyone who you think resembles a terrorist (like religious pilgrims).
In that case, you're no better than they are, and you are at cross-purposes with what FR is all about.
