If nothing else, Katrina makes the argument for biometric identification for all American citizens to be a compelling national interest. A lot of fraud is going on right now with these refugees, but far more is yet to come. The government ought to make fingerprints and photo ID cards a standard issue for all people seeking help in rebuilding in New Orleans and all across the Gulf Coast.
And, needless to say, with so many dead and possibly unidentifiable, a national standard for identifying our citizens is a must.
