The conversation between human and AI assistant.
Shipping: How does a shipper (USPS, UPS, FedEx) detect if illegal items (narcotics, explosives, etc.) are being mailed?
That's interesting. Are there any other methods they use?
Yes, they also use manual inspection of packages by trained employees who are trained to identify suspicious packages. Additionally, they use electronic monitoring and tracking systems that can detect abnormalities in packages, such as weight, size, or destination. These systems can flag a package for additional screening or investigation.
