The Border: If you build it, they'll still come: Border fence can't stem tide

kens5.com San Antonio: ""Every time we implement any new type of fencing we learn from the limitations of the last fencing that we had in place," says U.S. Border Patrol agent Colleen Agle. "The first generation was a lot shorter so people did have a lot easier time climbing over it, and it was also just sheet metal so it was very thin," Agle explains.

The oldest barrier along a particular stretch of border is known as a "picket fence" because of the white bars. Mesh was added later because people used to stick their hands through the bars, using them to climb over the fence, and then it would take just a few minutes to make it into town.

"We know that over time they’re going to defeat this fencing, this brand new fencing as well. But as of right now this is the best stuff we’ve got and it’s doing a much better job for us," says Agle." read more
