Is there a formal school somewhere that teaches a person how to torture? I mean you see all these movies and tv shows and they have "professionals"(ie 24,True Lies etc) Is that just Hollywood?
First of all, there is an expansive range of opinion on what exactly constitutes "torture". Some fruit-pies will define as "torture" any conditions which fall short of the treatment one might expect to receive as a guest of the MGM Grand's Presidential Suite. There is a difference between inhospitable or "tough" conditions and torture, although you'd never convince the fruits at Amnesty International of this.
If you are using Hollywood as your basis, then yes that is just Hollywood.
Philadelphia, Los Angeles, and Chicago police detectives in the 1940's routinely used more brutal torture methods than our military ever has. The militaries of other countries are rather notorious for their torture, not the United States. While our soldiers were being electrocuted, beaten, starved, hog-tied, strung from rafters, and killed in North Vietnamese POW camps, North Vietnamese and Viet Cong POW's were being held in comparatively humane conditions. Some one should have offed that bitch Jane Fonda the moment she stepped foot back in the states.
The military has taken a more scientific approach to extracting information without brutal methods, conducting studies of psychology, psychopharmacology, sleep deprivation, ploys, and "hard" interrogation methods that fall well short of the "torture" which are condoned if not celebrated in other countries.
