President Donald Trump wants to build a wall on the US-Mexico border to keep out “bad dudes” and worse narcotic drugs.  Albuquerque Journal investigative reporter Mike Gallagher has done a 6-part series on the international market for illegal drugs called The Cartels Next Door and says a wall won’t even slow down the cross-border traffic in cocaine, heroin, methamphetamine and the fentanyls.  Almost all of them, he says, are smuggled through legal Ports of Entry, the gateways through the wall.
