Though it is very "big brother" -- and I am against everything that smacks of that -- the thought of a child under the thumb of a maniacal pedophile makes me pause. If there was a way to remove it, I might consider it. Probably a better way would be some type of microchip that is minute enough not to be seen by a would be kidnapper (a cell phone would be gone in a hearbeat) and that is easily transferred from one piece of clothing to another instead of being implanted under the skin. My sister had Norplant (birth control) implanted. Though it was quite a few years ago, and I am sure the technology has changed, she had great difficulty in having it removed. I have to say that, in light of the way we are moving toward that police state, I do worry about the future greatly for my grandchildren.
