You ever been hit in the head with a bat? You ever been clocked in the eye with a tire iron? Ever been stabbed?
None of that really hurts all that much when it initially happens. So basically it's not effective torture.
Yes i've been hit in the head with a bat along with waterboarded.
I would consider hitting someone with a bat to get information far more torture than waterboarding.....cracked skull, bruising, cuts, concussion, death all can/do result from batting someone in the head, waterboarding on the other hand leaves no physical damage.
I'm sure getting hit in the eye with a tire iron and being stabbed are just as bad if not worse than the bat thing.
