Does anybody seriously doubt that:

1.This system will cost billions to set up ( several time more than whatever is quoted) and be expensive to use.

2.It's security will be severly comprimised several times, both with identity theft, and people breaking in to create false identities for themselves, for whatever reason.

3.We will still have serious problem of crime commited by people not registered in this scheme, as common criminals, illegal immergrants or terrorists.

I don't believe it will do much to prevent crime of any sort, but will cost a fortune and be a huge infrigement of our civil liberties.
