Screening means a reasonable examination of persons, cargo, vehicles, or baggage for the protection of the vessel, its passengers and crew. The purpose of the screening is to secure the vital government interest of protecting vessels, harbors, and waterfront facilities from destruction, loss, or injury from sabotage or other causes of similar nature. Such screening is intended to ensure that dangerous substances and devices, or other items that pose a real danger of violence or a threat to security are not present.
