Does a Border Wall Not Work Against Illegal Crossings at All?
Barriers work as part of a system with agents, technology and consequences; where they were built and manned, crossings fell and agents gained time.
The claim
Critics say a wall is a medieval answer to a modern problem. People climb over it, dig under it or cut through it, most illegal immigrants arrive by plane or overstay a visa, and the money would be better spent on technology, judges and asylum offices. A wall, they add, is a symbol and not a strategy.
The answer in three points
- A barrier is not meant to stop a determined person forever. Its job is to slow crossings so that agents have time to respond. A fence that buys minutes in a populated area turns an unseen crossing into an arrest, and that is the difference between a controlled border and an open one.
- Where barriers and enforcement were built together, as in the San Diego and El Paso sectors in the 1990s and 2000s, crossings dropped sharply and moved to remote areas where agents could focus. Cities on the border grew safer for residents, who had long lived with traffic through their yards.
- Walls are not the whole answer, and supporters who say they are make the critics' case. A working system also needs agents, sensors, quick hearings, and consequences for crossing illegally. Each part strengthens the others.
The numbers
- The Secure Fence Act of 2006 authorized hundreds of miles of fencing along the southwest border, according to the text of the law.
- U.S. Customs and Border Protection recorded about 2.5 million encounters at the southwest border in fiscal 2023.
- The Department of Homeland Security's Office of Homeland Security Statistics reports that most illegal entries are not visa overstays, and overstays are measured in the hundreds of thousands a year.
What they will say next
"Most illegal immigrants overstay visas." Visa overstays are a real part of the problem, and they require a different tool: entry-exit tracking and employer verification. It does not follow that a border crossing between ports of entry should be left open.
"Smugglers just go over or under it." Some do, and the wall forces them to use ladders, tunnels and time, which raises the risk and cost to them and gives agents a chance to catch them. A lock does not stop every burglar either, and nobody proposes leaving doors open.
"It costs too much." A wall is expensive. So is a system without one, in agent hours, in processing and in the harm done to border communities. The question is how it compares with the alternatives for the same goal.
"Private land and the environment complicate it." True, and a careful plan respects property owners, pays fair compensation and builds where it is most useful. That argues for careful planning, not for none.
"Border crossings have fallen without a wall." They rise and fall for many reasons, including enforcement and policy. A durable system has barriers, agents and rules all in place.
