"I love strong opponents! It's such fun to break their backs! said the Leningrad interrogator Shitov. And if your opponent (e.g. your prisoner) is so strong that he refuses to give in, all your methods have failed and you are in a rage? Then, don't control your fury! It's tremendously satisfying, that outburst! Let your anger have its way; don't set any bounds to it. Don't hold yourself back! That's when interrogators spit in the open mouth of the accused! And shove his face into a full toilet! That's the state of mind in which they drag Christian believers around by their hair. Or urinate in a kneeling prisoner's face! After such a storm of fury you feel yourself a real honest-to-God man!"
