DEA Polygraph of Confidential Source

[George W. Maschke]

As noted on the blog, in 2003, the Drug Enforcement Agency's Office of Professional Responsibility (OPR) instructed polygrapher E. Victor Perez to conduct a Peak of Tension test on a confidential source who allegedly received a classified DEA document from an employee at the U.S. Embassy in Bogota, Colombia.

I have a couple questions for any polygraphers reading this:

1) Do you think it was appropriate for DEA OPR to conduct a polygraph examination of the confidential source after 12 hours of interrogation? If so, why?

2) Given the case facts presented in Special Agent Perez's report, do you think it was appropriate for OPR to instruct him to use the Peak of Tension technique? Why or why not?
