Back in 1991 I was in Hong Kong and then traveled across the border into commie China. It was easy to cross that way. The Chinese guards spoke to our bus driver and our tour guide "Andy" (that was his western name, he told us), and they essentially vouched for us. We all had valid passports, and were all just tourists there to visit beautiful China! Okay, the guards said, and waved us through.
The next day we were returning to Hong Kong...and OMG! the line of parked trucks backed up for miles....miles I tell you. Probably 15-20 miles of trucks, pulled off on the side of the road. The drivers had tents and campfires going, camping out as the line literally inched along. Our bus was directed to a bus lane, and we arrived at the border behind just two other busses. We were told to get off the bus and enter a building for thorough check of our passports, travel papers, our pockets, any baggage we had (most of us had made purchases in China, souvenirs), and they put dogs sniffing for whatever on the bus. They climbed into the luggage department under the bus. They opened the hood and looked at the engine compartment. They searched every inch of the bus. We were ushered through into a café where we could order snacks, coffee, Pepsi! (yes, they had Pepsi!). I looked out the window and got a good look at the border crossing. The trucks, backed up for miles, were practically disassembled, the freight was opened, every box. The wall was a high concrete structure lined with machine guns....all pointing in! The Chicoms didn't fear an attack from Hong Kong (still a British colony back then), they feared a mass exodus of their own citizens.
We were then ushered to a train station where we boarded an express train back to Hong Kong City. Hong Kong was a province, much larger than just Victoria City, I think it was called. Hong Kong province was about 60 miles across and about 100 miles, north-south. It had small farming villages scattered throughout. We were staying on the Kowloon Peninsula, across from Victoria Island.
Anyway, the point of all of this is, we need to do something like that on the Mexican border. Build a solid, impassable wall, lined with machine guns all pointed outward! and have points of entry where EVERY vehicle is searched like the Chicoms searched those trucks and busses. No drugs could slip through....even Cheech & Chong would get nailed!
Yes, the cartels will still try and they will use boats, and planes, and submarines, like that Columbian drug lord used! They will fly drugs into Arkansas, like the Klintons did, and murder the DEA agents who were on to them....and yes, some drugs will still make it to our streets. That's a sad reality. The cartels will switch to crossing the Canadian border, if they have to. We will then just have to tighten up on our northern border then.
Have to fight the good fight.
