but you yourself just said that there are open sections... so how are they tunneling under a wall?

some of the tunnels were nearly 1000 yards long (over half a mile), going from cities in Mexico to the US...

only an idiot wouldnt see whats going on there...

and its more about the human traficking aspect than the drugs... like i said, drugs dont move, breathe, speak, ect... people do... and they dont bring them through ports of entry....

also, a "fence", would force smugglers to ONLY use ports of entry... beef them up, game over...

its a simple concept, but i understand why you dont get it...
