Texas to Adopt “Tangles” – a Warrantless Profiling and Geofencing Tool

​The Texas Observer reports that the Texas Department of Public Safety (DPS) signed a 5-year, nearly $5.3 million contract for the Tangles surveillance tool, originally designed by former Israeli military officers to catch terrorists in the Middle East.
 
In its acquisition plan, DPS references the 2019 murder of 23 people at an El Paso Walmart, as well as shooting sprees in the Texas cities of Midland and Odessa. If Tangles surveillance stops the next mass shooter, that will be reason for all to celebrate. But Tangles can do much more than spot shooters on the verge of an attack (assuming it can actually do that). It uses artificial intelligence to scrape data from the open, deep, and dark web, combining a privacy-piercing profile of anyone it targets. Its WebLoc feature can track mobile devices – and therefore people – across a wide geofenced area.
 
Unclear is how DPS will proceed now that the Fifth Circuit Court of Appeals in United States v. Jamarr Smith ruled that geofence warrants cannot be reconciled with the Fourth Amendment. If DPS does move forward, there will be nothing to keep the state’s warrantless access to personal data from migrating from searches for terrorists and mass shooters, to providing backdoor evidence in ordinary criminal cases, to buttressing cases with political, religious, and speech implications.
 
As the great Texas writer Molly Ivins wrote: “Many a time freedom has been rolled back – and always for the same sorry reason: fear.”
