More Lies...

Here is an article from Wired about not specifically eyemovements and lying but general mechanisms of lie detections - including facial heat, polygraph, erp, etc.
"Success remains elusive, however, and no newfangled lie-detection machines appear ready for prime time. Skeptics, meanwhile, doubt that any technology will improve much on the mixed record of polygraph machines, which are often used in the United States to screen employees and test the truthfulness of criminal suspects."

There has been a decent amount of success with ERP and fMRI but that may still be a little way off from completely replacing the polygraph. You would think if eyemovements were at all reliable that would be one of the topics which was high up on the investigation scale - doesn't seem to be mentioned much though except on "entertainment" or popular press sites.
