This debate is taking place right now between Gary Smith, who says he didn’t kill his roommate and Montgomery County prosecutors, who say otherwise.

However, many experts doubt whether the technology is ready for the real world, and judges have kept it out of the courtroom.
In a previous blog post we talked about some of the physiological factors of lying and fMRI scans.
