Fish or cut bait

As we continue to capture close associates of Zarqawi as part of our effort to roll up his deadly terrorist ring, it would be interesting to know which approaches to interrogation of these key terrorists liberal Democrats (and conservative Republicans for that matter) think should be permitted. For example, if the interrogators think that sleep deprivation would help produce valuable information should they be permitted to use this approach? I certainly think so. What say you, Senator Leahy?
