Trump's wall won't stop heroin from coming into the US - It’s a scene out of TV shows like Breaking Bad and Better Call Saul : A truck transporting legal goods (like ice cream) goes through the US border, sneaking illicit drugs through security inspections by simply hiding them — whether among the other products, a secret compartment, or some other tricky spot. Scenarios like this aren’t just the stuff of fiction; drug trafficking through a legal port of entry is how most illegal drugs make it into the US. And this kind of smuggling will be totally unaffected by a wall put in place to block illegal border crossings, showing that even the toughest border security measures may be next to worthless for dealing with illegal drugs.
