"The International Civil Aviation Organization, ICAO, has released a recommendation regarding a new specification for photos in passports," explained Suzanne Meunier, spokeswoman for the Canadian Passport Office. "What they say is that the facial expression should be neutral ... no smiling, no laughing, no frowning -- no expressions, basically." *
This will make it much easier for customs officers to identify someone from a photo. People will look as grumpy in the photo as they do in the customs lineup.
