Either the editor of this article misrepresented the source, or the source is lying (I doubt this considering his resume). When sources are first brought into an interrogation they are screened to ascertain their level of resistance, needs and wants, or anything else they may divulge that will give the interrogator an edge in the approach to actual interrogation. The appropriate methods are then employed by the interrogator based on the initial interview. Sources are NEVER automatically given food, water, tickets to Disneyland, or anything until this inital interview is done and the psychological state of the source is determined.
