In an delightfully ironic lesson why border protection is important for the US, an MSNBC crew was reporting on the prototypes of Trump’s proposed border wall near San Diego, when the interview was interrupted by a group of “migrants not from Mexico” hopping over the existing fence.

“What happened?” the MSNBC reporter shouts as a group of agents on horseback move in to catch border jumpers. “The people are crossing!”

“Almost on cue, a group of asylum-seekers, migrants not from Mexico, jumped over the existing fence to turn themselves in to border agents on horseback,” the narrator explained.

“It’s like, a small group of three people jumped over in the middle of the day,” he told a border patrol agent he was interviewing. “There’s a girl there in a pink backpack. Can you explain to me what’s going on?”

What's going on is that, as the border agent explained, it’s just another day at work fighting the battle to secure the nation’s southern border.

“This is the reality of every day border enforcement. The United States is still the draw, the ultimate draw, for people that have dire situations where they’re at,” the agent said. “We’re going to continue to witness this. It plays out on a regular basis for us.”

“And it did here just now,” the dismayed reporter replied, as first observed by the American Mirror.

Meanwhile, construction crews are currently erecting eight roughly 30-foot-tall prototypes for the president’s border wall in a remote section of the border near San Diego, where at least a half dozen illegal immigrants have been arrested while attempting to cross amid the construction, according to NPR. The prototypes currently include four made of solid concrete, four made of steel and concrete and one topped with spikes.

“Customs and Border Protection is paying $20 million to six construction companies from Mississippi, Maryland, Alabama, Texas and Arizona” to construct the models by the end of the month, after which CBP will evaluate them based on three criteria, NPR reports.

“We want a better barrier. One that is hard to scale, hard to penetrate and hard to tunnel under,” Roy Villareal, chief of the San Diego Border Patrol sector, told NPR. “We’re hoping innovation from private industry combined with our experience generates the next evolution of border security infrastructure.”
