I'll lead off and then invite Deputy Duheme afterwards.
As Scott just said, we have great collaboration with the same partners that he just mentioned in the U.S., including Homeland Security and ATF. On top of that we also have great collaboration, joint investigations with agencies like the Drug Enforcement Agency, for example. A lot of organized crime groups, once they've established successful smuggling routes across the border, even though their mainstay may be smuggling illegal narcotics, may also use those same smuggling routes for smuggling other contraband such as firearms. Sometimes we can get great intelligence out of organized crime investigations working with those types of agencies as well.
Mike, do you have anything to add?
