I know this has been talked about many times but I know the FBI or others that came up with the microchip for pets can come up with something for our children, something in their body that would ping off a tower or a GPS, I know this would not keep them from being abducted but at least they could be found quickly. I swear if I knew someone that could do this I would do it for my granddaughters, you can tell them about stranger danger but it is not enough, this would have to be inexpensive so all could have this device and you know insurance would not cover it, I bet John Walsh could get this done. I am so serious about this, my heart just breaks when children are hurt and their family, I would never make it through this horror. Is it a possibility? One child not brought home is one child too many.
