There are ways to discourage your enemies from bypassing your walls, but as illustrated above, they take a lot of motivated manpower.
The answer to the title question is on the bottom of the story.
When Trump began to tout how his big beautiful wall, later to become an ugly supposedly impenetrable wall, would stop anyone from crossing the border I didn’t write about it. However you’ll have to take me at my word that I predicted all the ways people would thwart its purpose when talking to friends. Now everything I thought would happen has happened. The Washington Post just confirmed this.
According to the Post “smuggling gangs in Mexico have repeatedly sawed through new sections of President Trump’s border wall in recent months by using commercially available power tools, opening large gaps using the cordless household tool known as a reciprocating saw that retails at hardware stores.” The Post says they cost as little as $100 but I found battery operated versions on Amazon for $60 and the steeling/concrete cutting blades are inexpensive too. These blades allow the saws to slice through one of the barrier’s steel-and-concrete bollards in a matter of minutes.
The bollards are tall and because they are attached at the top leverage makes them easier to push apart. Even if to correct this they are connected every few feet with steel rods these saws can still cut the connecting bars.
The other way the Post reports that people are getting to the other side of the wall is far more low tech. They are getting over it with methods that could have been employed by ancient Roman soldiers.
Agents in California and Texas said smuggling teams have also been using improvised ladders to go up and over the barriers, despite the risk of injury or death from falling; the tallest barriers are approximately the height of a three-story building. Some of the teams deploy lightweight ladders made from metal rebar, using them to get past the “anti-climb panels” that span the top of the barrier.
Once the lead climber reaches the top, agents say, they use hooks to hang rope ladders down the other side.
The rebar ladders are popular because the metal support rods are inexpensive and are skinny enough to pass through the four-inch-wide gaps between the bollards, making it possible for the smuggling teams to use them to scale the secondary row of fencing, according to agents. Rebar, easily purchased at hardware stores, typically is used within concrete as reinforcement.
There are various tools using leverage which can be used to bend metal bars apart but the easiest to obtain would seem to be a car jack.
Those seeking inspiration to get into the United States from Mexico to better their lives need only watch this 2004 video of Donald Trump. It was unearthed by The Guardian and played on The Trevor Noah Show. Below is the short version.
“Never ever give up, don’t give up, don't allow it to happen, if there's a concrete wall in front of you go through it, go over it, go around it, but get to the other side of that wall.” Donald J. Trump speaking at speaking at Wagner College where he was given an honorary doctorate in New York in 2004.
Here’s the entire 14 minute introduction and his speech. “The Trump name means superiority and quality.”
Grin and bear it, this is one for the history books.
