I agree that one should not rely on anything that can break, without having a backup plan. But that doesn't mean I refuse to own a gun because it might misfire.While I don't see a moral issue either, as basic phone plans include talking and txting, the moral issue is that the family should know where their 8 year old child is...school, a friend's house, etc. If an emergency should occur, the child should be taught where to go. I don't subcribe to the notion of relying on electronic means of communication in the event of an emergency
