Texas police invested in phone-tracking software and won’t say how it’s used

Texas law enforcement agencies are spending millions on a little-known phone‑tracking tool that aggregates location and other data from the open, deep, and dark web, while refusing to explain how it is used or audited. Commenters raise concerns about warrantless surveillance, “parallel construction” to launder illegally obtained leads, the broader erosion of Fourth Amendment protections, and the role of data brokers and tech platforms in enabling mass tracking. Some argue such tools help solve serious crimes, but many see a growing imbalance between state power and individual privacy, exacerbated by weak oversight and limited legal consequences for police misuse.

Concerns about surveillance and civil liberties

  • Many see phone-tracking tools like Tangles as inherently dangerous, especially for warrantless, population-scale tracking.
  • Strong worry that data is used to “find” probable cause rather than support existing evidence, undermining core rights.
  • Several fear a trajectory toward 24/7 surveillance and, eventually, control, making dissent or protest practically impossible.

Legality, warrants, and “parallel construction”

  • Multiple commenters liken this to “parallel construction”: using questionable data to guide investigations, then backfilling a legal-looking evidentiary trail.
  • Some argue police are now openly describing behavior they once tried to hide, signaling confidence that courts and the public won’t stop them.
  • Others note that tools used in cases like Jan 6 (geofence warrants) are already being challenged under the 4th Amendment; these newer tools seem even less constrained.

Data sources, dark web, and brokers

  • Debate over where Tangles gets location data: dark web, hacked records, or commercial data brokers.
  • One view: if data is bought from brokers, it may technically not be a “search,” shifting the blame to shady apps and weak privacy policies.
  • Others worry police could indirectly incentivize hacking (buying leaked telco data via intermediaries) to bypass judicial oversight; legality of this is flagged as unclear.

Utility vs abuse

  • Some note that location data is already used for beneficial purposes (transit planning, traffic analysis).
  • Others counter that “tracking the population without cause” is never acceptable, regardless of potential public-good applications.
  • Question raised whether the showcased example in the article actually demonstrates unique value, or just wastes money on flashy tech vs traditional warrants and cameras.

Constitution, policing, and accountability

  • Long tangent into constitutional interpretation, especially the 2nd Amendment and “originalism,” reflects broader distrust of how rights evolve with technology.
  • Several argue the U.S. lacks meaningful rule-of-law for police; sanctions are rare and often symbolic, though others cite consent decrees and liability insurance as partial checks.
  • Strong sentiment that secrecy might be appropriate against criminals, but transparency is essential to restrain government abuse.

Media framing, mental health, and discourse quality

  • Some criticize the article’s “shadowy” headline as clickbait and biased; others say that matches the reality of secretive surveillance firms.
  • One commenter worries such headlines exacerbate paranoia for people with psychosis; others respond that civil-liberties threats outweigh that concern.
  • Meta-discussion: complaints that HN is drifting toward Reddit-style, slogan-driven, politicized commenting; some want less politics, others say it’s too late.
  • A few emphasize the importance of funding local journalism, noting local outlets are doing this kind of watchdog work more than national media.
