You can watch the reaction of Binta Moussa-Davis, the wife, below starting at about the three-minute mark:?

Full burka was probably not the best choice for making a public plea about her husband's non-intention for terrorist activities. She would've been better off being off-camera than in full veil costume. I'e read that if anyone wants to become invisible - like say they'd robbed a bank or were wanted for anything, the perfect disguise is a burka because it is so offensive that everyone looks away. Hey maybe that would be a good halloween costume!
