Your tax dollars spent on voodoo

Not literally, but: the US Army is distributing handheld polygraphs to our soldiers in Afghanistan. Polygraphs simply do not work.

I'm totally in favor of doing this, if the soldiers are properly briefed.

The thing is, the Talibani and their supporters will believe the polygraphs work, and they'll be an effective bluff, like the famous cop-and-colander story.
