With an intelligently (dare I say "smartly") built border barrier, aliens don't make it into the United States. They have no due process claims; they don't need to be arrested, or detained, or put into an interminable court queue. They aren't here and therefore can't abscond. Finally, because they never made it in, they don't need to be repatriated at tremendous taxpayer expense (if and when that day ever arrives, years after the fact).
Todd Bensman, the Center's Senior National Security Fellow, discusses border walls in in foreign countries and his recent report on Hungary's border wall.
