Those much-vaunted helicopter parents are turning into black-helicopter parents. The image of parents hovering over their kids is morphing into the darker image of parents spying on their kids. Here is the latest bit of high-tech surveillance equipment being marketed to parents. A company inauspiciously named Bladerunner has begun selling a jacket with a GPS device sewn into the lining. For a mere $500 plus $20 a month, a parent can track a child, or at least his jacket, all day long. This is just a small addition to the family-friendly arsenal. We already have a full range of cellphones equipped with GPS. Indeed, the most common cellphone greeting is not "How are you?" but "Where are you?" Parents are being sold the idea that they can trust but Wherify - the name of one of the many manufacturers offering services that beam their children's whereabouts to their cellphone.
