SMART WALL
These methods of control and surveillance not only point outward but inwards as well. CBP is the largest law enforcement agency in the US and their jurisdiction exists within 100 miles of the border, encircling a region where nearly 2 out of 3 Americans live. This grants them abilities to conduct warrantless searches and question citizenship status of whoever they stop - both of which are in violation of the 4th amendment.
In addition to CBP, local law enforcement agencies receive money from the DHS to carry out border enforcement duties under Operation Stonegarden. This operation provides funds to pay overtime to officers and purchase equipment for border-enforcement purposes. This equipment includes IMSI towers, the same towers in use at the Salvadoran border. These towers are employed by law enforcement agencies in 27 states as well as CBP and ICE.
Recent proposals include constructing a fiber optic cable along the southern border. While this would help rural communities by providing them with previously unavailable high speed internet access, this kind of infrastructure would also enable more pieces of surveillant technology to be deployed in more remote places.
For those passing through the border zone, which is not only migrants but American citizens, the virtual wall through its very operation, dehumanizes and objectifies anyone it detects. As the technology becomes more sensitive and sophisticated, migrants will continue to make the journey but will be forced to venture further out into harsher environments and to take part in dangerous activities hoping to avoid detection.
