Polk County, Florida, schools allowed company to scan students’ irises. School officials found nothing suspicious about no parents calling or opting out of iris scans at three different public schools. Parents were alerted in a letter sent “on Friday, May 24, although the letters were dated for delivery the day before. Parents received the letter on Friday after the school officials had gone home, and it was a long weekend with Memorial Day holiday, “when exactly did this program get suspended?” The program was supposed to be a pilot security program to be tested on 17 school buses.”]
