So you're saying it's not possible to track the tags from off school grounds? And you're basing this on your interpretation of what that news reporter says? The news reporter is not educated in this matter any more than I am. The reporter might be informed, but he'll be informed by whoever he talks to at the school or from the tag company, which may give a slightly one-sided view. This goes some way towards balancing the news story, with the parents and students being on the opposing side.
I know it exists already at other places, and that only makes it worse. The whole story is about students and parents protesting, and they're the one's who have to wear the tags, so I think they're the ones who's opinion about wearing them should be listened to. Not yours or mine. It's making money at the expense of people privacy, and experimenting with children. It's wrong in my opinion.
If you think I sound paranoid then fine. But i'd rather come across like that than be someone who just says "yeah whatever, I don't care" and lays down and submits. At what point do you say enough is enough?
