Why interdiction fails

So they're talking about building a wall along the Mexican border to keep out illegal immigrants and presumably to also to thwart drug smugglers. It's never going to work, not as long as border guards are tempted by the big bucks of black market bribery.

U.S. Customs Inspector Lizandro Martinez is behind bars, suspected of taking more than $1 million in bribes while waving through more than 50 tons of drugs — more than his law-abiding colleagues seized at eight South Texas ports of entry in an entire year.

Like they say, everybody has a price and a million bucks is tough to turn down for simply waving through a few trucks. More proof that the only way to end drug smuggling is to legalize drugs.
