One of the hallmarks of GOP nominee Donald Trump’s platform is a wall along the U.S.-Mexico border. Using natural barriers where feasible, his plan is to build a 35 foot to 40 foot wall 1,000 miles long. While the idea has been much discussed on the campaign trail, from a border security perspective, the details and implications have been insufficiently debated. Setting the rhetoric aside, there are many aspects to a border wall that Americans need to know.
1. Illegal border crossings will continue. There is a perception that if the wall is high and long enough, it will be insurmountable. But a wall of any size only pushes smugglers and others to dig deeper tunnels or build taller ladders. We know this from experience. When the current 18-foot fence was installed in McAllen, Texas, Border Patrol officers began collecting 19-foot ladders in such number that station supervisors said to stop bringing them in.
