Walls of Shame : The US-Mexico Border Wall

The structures, fences and walls that mark the border between the United States and Mexico as President Donald Trump reiterates his promise to build a wall along the U.S. border with Mexico.

A border of more than 3,000km separates the US from Mexico - but it is defined not only by physical barriers made of concrete and steel but by an immigration policy which is failing to address the issues behind illegal migration. Although the US has spent billions of dollars on border enforcement, the lure of work sees illegal migrants enter the country at a rate of 850,000 a year.
