Last month Time magazine did an article suddenly discovering that the U.S./Mexico border is a sieve that lets millions of people and tons of drugs pass across it every year. In an age of terrorism, this looks like a disaster waiting to happen. If migrant workers and drug runners can cross the border, then obviously terrorists can do so just as easily.
A look at the empirical evidence, however, suggests just the opposite. Comparing Mexico to our other border with Canada, we find that while several dozen suspected and actual terrorists have been caught crossing over from Canada none have been caught trying to cross over from Mexico. Moreover, none have been found in the U.S. after having passed through Mexico. If the Mexican border is such a security sieve why do the terrorists not flock there in droves?
The answer is easy. Mexico isn’t the place most Americans imagine it is.
