Uh...how is this liberal?
RF equipment isn't all that expensive, it keeps the kids in the school and the wierdos out. Besides, making a 1st grader wearing a big, ugly tag on their shirt is a whole lot different than surgically implanting them with something, or all of that "mark of the beast" stuff.
What good is requiring a child to wear an RFID badge. Badges are easily removed defeating the "intended" purpose? Appears to be simply another waste of time and potentially taxpayer funds.
