I thought this essay in the Post-Gazette a couple weeks ago was very well reasoned and well written, by someone who clearly knows whereof he speaks.
"…government sanctioning of mistreatment of prisoners by its intelligence officers is an essentially evil act committed in the name of self-defense, which has propelled our great country down a slippery moral slope and imperiled us further."
Where have the days gone? 
I really liked this article. Thank you for sharing it.
