In his State of the Union address last week, President Joe Biden urged Congress to pass a bipartisan immigration bill “with the toughest set of border security reforms we’ve ever seen.” The bill would have, among other things, funded “100 more high-tech drug detection machines to significantly increase the ability to screen and stop vehicles from smuggling fentanyl into America.” The high-tech drug detection machines are actually just X-rays — really high-res ones, but X-rays all the same.
'CBP hopes to scan 40 percent of passenger vehicles and 70 percent of commercial trucks by the end of 2025' Most people are waved through after answering questions about what they’re bringing across the border and showing CBP officers documentation that shows they can legally enter the US, usually in the form of a passport, green card, or visa. Truck drivers are also required to submit a manifest detailing what they’re carrying in their trucks before they arrive at the port of entry.
