As reported on the blog (https://antipolygraph.org/blog/2016/05/22/dod-polygraph-operator-says-polygraphs-tripled-post-snowden-mental-countermeasures-a-tough-thing/), in a recent presentation to a group of law students, a polygraph operator for the U.S. Department of Defense (likely NSA) stated that post-Edward Snowden, the number of polygraph screenings conducted annually by DoD had tripled. From May 2010 to April 2011, DoD conducted over 43,000 polygraph screenings.
