US to collect fingerprints and eye scans from Canadians, Mexicans
The US may soon require Canadians and Mexicans to provide biometric samples as they depart the country. Proponents claim that this new system will allow security officials to check the samples against a known-terrorist watch list. Opponents question the necessity of requiring the data from persons who are leaving the country in light of the program’s expense. The US has already installed so-called “non-intrusive” devices on the Canadian border, such as radiation detectors.
