Smugglers have found an easy way to get through the vertical steel tube Mexican border wall. From https://www.washingtonpost.com/national/smugglers-are-sawing-through-new-sections-of-trumps-border-wall/2019/11/01/25bf8ce0-fa72-11e9-ac8c-8eced29ca6ef_story.html [washingtonpost.com]

The breaches have been made using a popular cordless household tool known as a reciprocating saw that retails at hardware stores for as little as $100. When fitted with specialized blades, the saws can slice through one of the barrier’s steel-and-concrete bollards in minutes, according to the agents, who spoke on the condition of anonymity because they were not authorized to speak publicly about the barrier-defeating techniques.

After cutting through the base of a single bollard, smugglers can push the steel out of the way, creating an adult-size gap. Because the bollards are so tall — and are attached only to a panel at the top — their length makes them easier to push aside once they have been cut and are left dangling, according to engineers consulted by The Washington Post.

In other words, no one did any serious pen testing on the wall design, or it would have been obvious that with all that leverage, the top tie-in was easy to flex. Who will Trump fire next?

Your submitting AC guesses that the first bollard/column/tube was cut within a week of the wall construction. A careless user failed to push it back into place after going through, so it was finally spotted. C'mon guys/gals, were you born in a barn?
