National and international legal prohibitions on torture derive from a consensus that torture and similar ill-treatment are immoral, as well as impractical, and information obtained by torture is far less reliable than that obtained by other techniques. Despite these findings and international conventions, organizations that monitor abuses of human rights (e.g., Amnesty International, the International Rehabilitation Council for Torture Victims, Freedom from Torture, etc.) report widespread use condoned by states in many regions of the world. Amnesty International estimates that at least 81 world governments currently practice torture, some of them openly.
