Waterboarding

Today's Boston Globe's editorial is the most persuasive I've seen so far on the matter. Here's an excerpt:

"In 1901 in the United States, the military court-martialed and sentenced to 10 years hard labor a US major who had waterboarded a prisoner in the Philippines during the Spanish-American War. The United States officially outlawed the practice after World War II, when the Germans and Japanese had both used it against Allied troops. The Allies executed eight Japanese officers for waterboarding British prisoners and sentenced another to 15 years hard labor for waterboarding a US civilian, among other crimes."
