>>Polygraph hooked up to a politician. Hmmmm....which one vanishes in a cloud of smoke first?<<
It'll never work... don't they to tell the truth for correlation and actually feel guilty when they lie?
Seriously, I don't think I would take a polygraph on general principle.
BTW, if this is a report about the police misconduct why are they hiding it in the first place?
That's nice.
I don't really think what you would do matters much in this case.
Besides, should you fail ... I would call for your execution. ;)
