Just kill the people who do this crap, as for the GPS etc. No way in hell should they do that to children soon that would mean everyone has a GPS device in them and that would mean that institutions would have too much knowledge of our where abouts. Yes, that could cut down a lot of problems. You would know who was where during a crime etc. but the rights of too many innocent people would be infringed upon.

There are many problems in the world and taking some away to help solve other ones, just makes new ones.
