I would like to see a row of jersey barriers with the concertina wire bolted to the top. It would make a formidable barrier some 7 feet high and be immovable by crashing a vehicle through it.
YOUR WISH IS MY COMMAND
Jersey barriers COMPLETE WITH ATTACHED RAZOR WIRE staged at the border for installation
THIS IS A GAME CHANGER...KIDOS TO PRESIDENT DONALD J. TRUMP the Great.
