also, however, i do think the woman should have to take the driving test again to see if she can drive with the burqa.
Not a solution unless you equip every cop and clerk with the technology to tell one thumb print from another at 30 feet away as well as they could between faces . . . and then give them a lifetime of informal training in thumbprint differentiation.
I'll look forward to seeing those thumbprints of the FBI ten most wanted on the Post Office bulletin board too.
Human face recognition may not be perfect, but it has some huge advantages for security purposes. A thumbprint is no substitute, though it's obviously nice to have in addition.
