The Los Angeles Times Editorial Board, in a Mar. 25, 2017 editorial, "Pretty Much the Only Thing Trump's Border Wall Will Block Is Common Sense," available at latimes.com, stated:

“If it’s built, the project will be a boondoggle of legendary proportions and likely will become the subject of historic ridicule. Why? Because Trump’s silly wall can’t possibly address much of the problem he seeks to fix… Trump has milked the melodrama of a border wall, but he ignores the likelihood that it would be ineffectual at stopping people from entering the country without permission. Human migration routes are like rivers: If they hit an obstacle, the flow finds a way around it. So a wall will just lead smugglers to find new routes and methods — planes, boats and 31-foot ladders for a 30-foot wall — even as it is being built, further undercutting confidence in the barrier’s effectiveness. Nor would Trump’s wall address the growth in illegal immigration from Asia, which outpaces immigration from Latin America… Perhaps most important, a wall could do nothing to halt the growing trend of people entering the country legally (often by plane) and then not leaving, which by some estimates accounts for as much as half of the undocumented immigration.”
