Some schools are already doing it!
=============
Many schools have security systems that include cameras sending live feeds that are monitored by security personnel.
The AP reports that some Lockport, NY schools are going a step further by implementing facial recognition technology that checks each face against a database of expelled students, sex offenders, disgruntled employees and other possible troublemakers.
In addition, the system can be programmed to scan for some weapon “tells” (think: guns or knives in waistbands) and can be matched against a complete file of student and faculty pictures.
Though the system has potential life-saving benefits, some folks are opposing it…
