Meeting the enemy

Former Soviet dissident Vladimir Bukovsky, writing in the Washington Post in 2005:

Every Russian czar after Peter the Great solemnly abolished torture upon being enthroned, and every time his successor had to abolish it all over again. These czars were hardly bleeding-heart liberals, but long experience in the use of these "interrogation" practices in Russia had taught them that once condoned, torture will destroy their security apparatus. They understood that torture is the professional disease of any investigative machinery.

[...] Investigation is a subtle process, requiring patience and fine analytical ability, as well as a skill in cultivating one's sources. When torture is condoned, these rare talented people leave the service, having been outstripped by less gifted colleagues with their quick-fix methods, and the service itself degenerates into a playground for sadists. Thus, in its heyday, Joseph Stalin's notorious NKVD (the Soviet secret police) became nothing more than an army of butchers terrorizing the whole country but incapable of solving the simplest of crimes. [...]

So, why would democratically elected leaders of the United States ever want to legalize what a succession of Russian monarchs strove to abolish? Why run the risk of unleashing a fury that even Stalin had problems controlling? Why would anyone try to "improve intelligence-gathering capability" by destroying what was left of it? Frustration? Ineptitude? Ignorance? Or, has their friendship with a certain former KGB lieutenant colonel, V. Putin, rubbed off on the American leaders?
