Yes, quite a few. In the instances of our southern border, our U.S. Border Patrol has used biometrics quite successfully to deter narco-trafficking. We put a camp along the northern Mexican border. We're constantly travelling to and from the border states—Texas, Arizona, even California—and once we started using more of our biometric capabilities, the correlation between implementing biometric capabilities and arrests of narco-traffickers went up. In one instance, as individuals came across one entry point, the biometric data would allow you to quickly corroborate that individual with his previous attempts at other entry points in other states. That cross-referenced the information and allowed law enforcement to quickly apprehend those individuals. In the past that would have been a difficult thing to do, considering different law enforcement procedures in different states. It was a difficult process, but it has become much more streamlined and efficient.
