“As a border patrol agent, I can tell you: walls do work,” a U.S. Customs and Border Patrol (CBP) attests, citing the success of barriers built on the San Diego border, in a CBP video.

In a video explaining why borders walls are an essential component of border security, the agent recounts how the institution of border walls in San Diego has resulted in a 87 percent reduction in annual apprehensions of illegal aliens – from 560,000 to 68,000:

“Consider San Diego. In 1992, agents in San Diego Sector apprehended more than 560,000 illegal migrants. That was only along a sixty-mile stretch – just three percent of the entire U.S.-Mexico border.” “In 1996, and again in 2006, bipartisan legislation authorized the U.S. government to build border barriers. And, once built, the barriers made a world of difference. “By 2010, apprehensions in San Diego have fallen from half a million to just 68,000 – an 87 percent reduction.”

The agent also explains how border security measures, such as border walls, have benefitted the environment and also transformed a “lawless wasteland” into thriving communities:
