From a border perspective, it's challenging, in that drugs are moving around the world all the time. What we're grappling with, alongside our B5 partners at the World Customs Organization, are small packages. As we've seen, a handful of fentanyl pills through the mail can become many doses out on the street and lives lost. We are working very closely with our partners. We recently talked to courier companies that don't want to be shippers of lethal drugs themselves, and don't want a pile of new reporting rules put on them. We all recognize that balance is needed between the supply chain and stopping drugs from coming in small packages.
That's an area we're focusing on and getting at through intelligence and targeting. At any one time, it's risk-based—looking at what's coming in and what's going out, but also grappling with the significant post-COVID increase in small parcels that are transiting the world at any one time.
