WASHINGTON—National Water Watch, a Washington-based conservation group, criticized the government's use of waterboarding Monday, calling the practice of stuffing a cloth into a detainee's mouth, immobilizing him, and pouring water over his face and body to simulate the sensation of drowning "a tragic waste of resources." "The idea that the United States could condone the despicable act of squandering several pitchers of water is shameful," NWW spokesman Gregory Hammil said. "It is amoral, unconscionable, and in direct opposition to all internationally recognized water- saving techniques." Hammil recommended the government switch to more eco-friendly means of enhanced interrogation, such as waterboarding with a return-hose device in order to reuse old water, or simply beating suspected terrorists to a bloody pulp.
