Really? That's their story? Here it is:
Davis told me that “it is a mistake on our part” that a notification letter to parents did not go out on May 17. He blamed a secretary who had a “medical emergency.” Instead of verifying that parents received the letter and ensuring that any families who wanted to opt out had a chance to so, the schools allowed officials from Stanley Convergent Security Solutions to take iris scans of an unknown number of students as part of a “pilot” security program for students who take the bus to the three above-named schools.
Wouldn't you expect this effort to require a returned consent form? And do we have to take them at their word that all this data has been destroyed?
