There are those who want to shoot drugs into their veins, and there are those who want to shoot drugs over the American border with a nice little cannon. There is now evidence of artillery pieces being used by Mexican drug lords to fire cans of drugs over the American border in order to get their wares to market without worrying about US Border Patrols. The American government prefers spending billions of dollars to capture those seeking to deliver drugs in our nation, the only one who makes money out of these deals are drug lords.
Republicans want a secure border. At this very moment there are probably hundred tunnels under our border being used to smuggle drugs and even people. Build a fence, someone will just jump over the fence. Make drugs illegal, someone will smuggle in drugs. The bad guys always win.
