Invisible Walls

Uncovering hundreds of surveillance experiments along the US-MX border.

Today, dozens of defense contractors are testing out new surveillance technologies along the US-Mexico border. This activity, however, lays largely hidden. By examining thousands of public records, this project seeks to reveal the extent of this emerging infrastructure and to document the companies and physical locations involved. Using the techniques of investigative and open source journalism, Invisible Walls is part of a long term research project about the politics, policing and mapping of the US-Mexico border.
