biometric identifier is extraordinarily prone to error. it often misidentifies individuals and you can imagine the circumstances that would result if police misidentified an innocent person as a criminal. jon: but there are also, well, there is also a component of it that allows you to do iris scans. iris scans are as unique as fingerprints, right? iris scans are quite unique but they, there isn t a large database or repository of iris scans available to compare against at this point. that s why the facial recognition is an attractive technology for the vendor to propose because there are more mug shots and facial recognition data out there as opposed to iris scan data. but the predominant use of this technology as it will be employed in the field will be the facial recognition component, not the iris scan component. jon: so your concern has more to do with the possible errors that are made rather than what you see as an invasion of privacy?
