Well this quikly brings to mind something my grandma used to say.

"The path to hell is paved with good intentions."

This and the RFID thing for criminals, along with infants (to protect them from being kidnapped), screams population control to me.

While all admittedly good reasons for doing these measures, actually doing them sets presedents for further such actions.

I dont trust it more than I disagree with the reasons for it.
