Advances in lie detection technology raise important and tricky new legal questions, especially in terms of criminal procedure. This article examines several types of brain-scan-based lie detection, both those being sold now and those that are still several years away from in-the-field use, in terms of the protections of the Fourth and Fifth Amendments. Focusing on the most developed of the technologies - FMRI - the article concludes that proper use of such lie detectors violates neither the Fourth nor Fifth Amendments.
