Whistleblower Says Border Walls Are A Good Deterrent For Illegal Immigrants

 December 15, 2023

A whistleblower's revelation is stirring up the debate over U.S. border policies.

A 2017 internal memo from the Department of Homeland Security (DHS) suggests that border walls are the most effective way to deter illegal immigration.

The memo, obtained by the Immigration Reform Law Institute (IRLI) through a public records request, was originally drafted for then-Acting Customs and Border Protection (CBP) Commissioner Kevin McAleenan. It focused on examining 25 key areas along the U.S.-Mexico border, concluding that in each sector, a physical barrier was the best method to curb illegal crossings.

Exploring the Controversy of Border Wall Effectiveness

This finding starkly contradicts President Biden's stance. He has frequently labeled the border wall as ineffectual and a waste of taxpayers' money, a view that led to the halting of the wall's construction upon his taking office in January 2021.

Despite this, under Biden's administration, a new border wall is being planned in Starr County, Texas. This move is in response to the increasing waves of illegal immigration in the area, showcasing a potential shift in the administration's approach to border security.

During the Trump administration, approximately 370 miles of new border wall were erected, with 80 miles of these in previously unfenced areas. The remaining 290 miles involved replacing older, less effective barriers. However, over 60% of the nearly 2,000-mile southern border still lacks a physical barrier.

Public Opinion Reflects Support for Border Walls

A Fox News poll from October indicated that a significant portion of the American populace supports the idea of further border wall construction. The poll revealed that four out of seven registered voters favored the continuation of DHS-led border wall projects.

These statistics are pivotal as they reflect a disconnect between public opinion and the current administration's policies regarding border security. This gap is especially notable given the increasing concerns over illegal immigration and border control.

IRLI Executive Director Dale Wilcox, commenting on the DHS memo, stated,

"For every area of the Southwest border examined, the audit determined that a physical barrier was not only the best option for disrupting irregular migration, but also the most cost-effective, as compared to alternatives such as electronic sensors."

Reactions and Criticisms of Current Policies

Wilcox further criticized the Biden administration's initial move to cease wall construction, labeling it as the first in a series of "catastrophic mistakes on immigration." This critique reflects a broader discontent among some factions who see the wall as necessary for national security.

Matt O'Brien, IRLI Director of Investigations, echoed similar sentiments. He questioned the motives behind the Biden administration's reluctance to embrace physical barriers along the southern border, urging Americans to consider the implications of such a stance on border security.

The DHS memo's findings and subsequent reactions highlight the current administration's significant policy dilemma. Balancing public opinion, expert analysis, and political ideology has proven to be a complex challenge in addressing the persistent issue of illegal immigration.

A Look at the Broader Implications

As the U.S. continues to grapple with the challenges of border security and immigration reform, the revelations from the DHS memo offer a critical lens through which to assess current and future strategies.

The efficacy and cost-effectiveness of physical barriers, as outlined in the memo, place the government at a crossroads. Deciding the best course of action requires not just political will but also a nuanced understanding of the multifaceted nature of border security.

This situation underscores the ongoing debate in American politics over how best to manage and secure the nation's borders, a debate that has implications not just for immigration policy but also for national security and international relations.

  • A significant portion of the public supports further construction of border walls.
