It would sure be a whole lot better than what we know have – or don’t have. There are miles and miles of nothing but barbed-wire fences and some of even less. And we don’t even need to talk about sections of the Rio Grande River where they wade across in broad daylight.
But instead of facing an old broken down chain link fence, the would-be illegal aliens faced a border wall, which had been built piece meal over the years by the Border Patrol with the public support of the congressional delegation from Southern California and other elected officials who wanted to stop illegal immigration. At that moment I saw for myself that if it wasn’t for that border wall—and the ubiquitous presence of the men and women of the Border Patrol—that the caravan would not have stopped in its tracks in Tijuana, but would instead be well within the U.S.
