The 9/11 attacks in New York marked the beginning of a precautionary era, which has directly affected the operations of international agencies and homeland security authorities. Before this, the main priority of the U.S. Customs and Border Protection was simply to prevent the smuggling of illegal substances into the country and to avoid importers from misclaiming the value of imported goods. CBP’s responsibilities have since shifted and extended to protecting the country and monitoring any security risk that may come in from international grounds.
Nowadays, the U.S. Customs targets, pulls, and examines any questionable shipment that enters the United States. With an automated scoring and flagging system, Customs inspectors are able to identify and review potentially faulty shipments.
