Of course, none of these technologies are foolproof. Nor are they immune from tampering, hacking or user bias. Nevertheless, they have become a convenient tool in the hands of government agents to render null and void the Constitution’s requirements of privacy and its prohibitions against unreasonable searches and seizures.
Consequently, no longer are we “innocent until proven guilty” in the face of DNA evidence that places us at the scene of a crime, behavior sensing technology that interprets our body temperature and facial tics as suspicious, and government surveillance devices that cross-check our biometrics, license plates and DNA against a growing database of unsolved crimes and potential criminals.
The government’s questionable acquisition and use of DNA to identify individuals and “solve” crimes has come under particular scrutiny in recent years. Until recently, the government was required to at least observe some basic restrictions on when, where and how it could access someone’s DNA. That has all been turned on its head by various U.S. Supreme Court rulings, including the recent decision to let stand the Maryland Court of Appeals’ ruling in Raynor v. Maryland, which essentially determined that individuals do not have a right to privacy when it comes to their DNA.
