When I think about this question... it centers the debate exactly where I like it to be centered.
Nobody has ever died from waterboarding. It leaves no physical scars and it's not physically painful.
People die from tasering.
two days ago it happened again. It's extremely painful and often leaves physical evidence if not scarring.
How is it that we are having a debate about torture and yet tasers are in such common use that we see it done on the news almost daily?
