India is convicting people based on brain scans.
From the story:
Even as the debate continues over using scans to trip up obfuscators, researchers are developing new uses for the technology. No Lie MRI, a company in California, promises on its Web site to use the scans to help with developing interpersonal trust and military intelligence, among other tasks. In August, a committee of the National Research Council in Washington predicted that, with greater research, brain scans could eventually aid “the acquisition of intelligence from captured unlawful combatants” and “the screening of terrorism suspects at checkpoints.”
“As we enter more fully into the era of mapping and understanding the brain, society will face an increasing number of important ethical, legal and social issues raised by these new technologies,” Mr. Greely, the Stanford bioethicist, and his colleague Judy Illes wrote last year in the American Journal of Law & Medicine.
If brain scans are widely adopted, they said, “the legal issues alone are enormous, implicating at least the First, Fourth, Fifth, Sixth, Seventh and 14th Amendments to the U.S. Constitution.”
“At the same time,” they continued, “the potential benefits to society of such a technology, if used well, could be at least equally large.”
If this don't scare the crap out of you, you need your brain scanned.
