I don't care if she knows where I am and it makes her feel better knowing she can find me. Her phone number is on my 911 gadget I have that I can activate anywhere in my house to automatically call 911. It calls 911 and then calls her.
While all that technology is available now, that is a good thing, however, Hussein's “spys” could find me, too. A pox on Hussein.
Criminals could do the same thing.
Probably are and have.
