There's just no doubt in my mind - under any set of rules - water boarding is torture.
When I was a kid, a pickleball hit me in the back of the head, and I had memory problems. I was in a boarding school and the nuns gave me poems to remember to try and get the memory going again.
I studied with a blind teacher from about 5 until I was 16, at two different schools. From the age of 12 until 16, I was in a boarding school-which, I believe, at that time was compulsory for blind children.
