Real ID has been amended (slightly):

One criticism of the Real ID legislation was that it exposed battered spouses to discovery. They might be hiding out, but the law required them to make their current address rather public, as it must be on the driver's license and in the state data base. This story is GOOD NEWS:

In re-authorizing the Violence Against Women Act (VAWA), congress included an amendment to deal with this issue. I read about it in Mother Jones:

Provisions in Rep. James Sensenbrenner’s (R-WI) REAL ID Act mandated that all state driver's licenses and ID cards contain a physical address. Previously, domestic violence victims could register a P.O. Box in order to hide their whereabouts from their abusers. Advocates say REAL ID's physical address requirement would put victims at greater risk, and succeeded in inserting language in VAWA to remedy the problem.

Alabama, are you listening? (Alabama just proudly installed new systems that they believe will make them compatible with the Real ID act. I wonder if their new software allows women to give a P.O.Box address. It's possible they're on top of this.)
