Quick Summary

James Cordero, 44, stumbled upon a hidden camera in an abandoned trailer on a remote backcountry road near San Diego, which led him to discover a vast surveillance network along California's border. The cameras, numbering up to 40, feed information into Trump administration databases and have raised concerns among privacy experts, civil liberties advocates, and humanitarian aid workers about government overreach and state law conflicts. According to Cordero, the cameras pose a risk to his volunteer group that provides aid to migrants in the area, who could be detained by agents for simply being tracked or pulled over. The surveillance network was enabled after California granted permits to federal agencies to place license plate readers on state highways in 2021.

Story summary

James Cordero, a 44-year-old man, was driving on a remote stretch of road in San Diego County when he noticed an abandoned trailer. Upon investigation, he found a hidden camera that was part of a larger surveillance network monitoring the license plates of drivers passing through the area. This discovery led him to uncover dozens more cameras in trailers and construction barrels along border roads in San Diego and Imperial counties. The cameras are believed to be part of a system installed after California granted permits to federal agencies, including the Border Patrol, to place license plate readers on state highways during the Biden administration. Now, up to 40 cameras may be feeding information into a surveillance network that was also established during the Trump administration. The Electronic Frontier Foundation and 30 other organizations have called for these permits to be revoked, arguing that the cameras are an invasion of privacy and do not serve any legitimate purpose.
