USA Today reports that more than 2,100 sheriffs departments in 27 states are doing iris scans and creating searchable databases “to identify sex offenders, runaways, abducted children and wandering Alzheimer’s patients.”
“This is the wave of the future,” said Sheriff Greg Solano of Santa Fe County, N.M. “This will become as common as fingerprinting.”
It’s easy to see the benefits:
Camaras use infrared light to make digital images so detailed they can tell the left eye from the right and spot differences in the eyes of twins [hey, do identical twins have identical fingerprints?]. The databases apparently can be searched in seconds, whereas fingerprint searching can take days and DNA testing can take months.
