Since the troll persists in claiming that torture "works" to get information, here's an explanation of why torture does not "work".

A specific example of its failure: when US agents tortured Ibn as-Sheikh al-Libi, he said what he knew Dubya wanted to hear. This helped Dubya start a war of aggression whose harmful consequences continue to ramify in Iraq, Syria, and elsewhere.

But even if torture did "work" in a narrow sense, it would be a vicious crime, and the harm it does would spread.

Practicing torture implants an inhumane attitude, which then manifests itself in a range of inhumanity: general cruelty to all prisoners, imprisonment without trial, collateral murder, and other atrocities.

These atrocities cause great suffering directly. They also provoke hatred. How many jihadis have been provoked by Guantanamo and US torture? Surely thousands.
