Until the publicity about torture in Guantanamo Bay and elsewhere I was unaware that there were schools in the USA which still have corporal punishment....and there are some horrific pictures of the injuries caused by "paddling" as it is quantly known.
There are some photos of this on an american site which suggest it goes rather beyond "six of the best" and is probably very good training for people who will be ordered to use "authorised methods of persuasion" on terrorists later in life.
