This strikes me as paranoid and weird: An Phoenix middle has installed cameras that scan the biometrics of visitors, looking for sex offenders and missing children. The Arizona Republic reports:
Sheriff Joe Arpaio said the cameras cost about $3,000 to $5,000 for a school to install and will not violate the privacy of anyone not already in the Arizona sex offender or in the national missing children databases, including possible abductors of missing children. If the camera registers a possible hit, the Sheriff’s Office is quietly alerted and will send a deputy or police officer to investigate.
. . . The system scans 28 facial features and matches them against logged images in the databases. School personnel will not know about the alert, and images that do not match the databases are erased, with no permanent recording.
The odds of catching a child molester or finding a missing child are smaller than the risk of creating a false sense of security and a complacence about ubiquitous monitoring.
