anyone will crack under prolonged interrogation
I would probably spill the beans at that point. In fact I would give everyone up the second they started strapping me into a chair "Yes, it is fucking safe!". The only thing is, how does the torturer know that what is said is true? I get that in some circumstances you can maybe check right away, but if you can't then how do they know the, er, subject isn't just telling them something that they want to hear?
