I was browsing through a book on Catholicism, as you do, and was struck by this description of one of the Spanish Inquisition's many interesting habits:
'Prisoners' hands would be tied behind their backs and their bodies then hoisted off the ground. They would be left suspended for hours or days until they were ready to 'confess' their sins. In another [torture method], the accused would be strapped to a trestle table, with their feet higher than their heads, while the priestly inquisitors would pour water down their throats.'
Go and see Moazzam Begg speak next week, I urge you.
