Millions of people have submitted oral cheek (buccal) swab samples to companies like 23andMe and Ancestry hoping to use their DNA to trace their ancestors and locate relatives in a process known as genetic genealogy. By comparing their DNA to that of other customers, the companies can determine whether, and to what degree, two customers are related. By comparing the DNA to that of known historic figures and their descendants, the companies can determine whether a customer has a famous ancestor. It is also possible to determine what geographic regions the customers’ ancestors came from and susceptibility to some diseases.
More recently, law enforcement has been using the information in the same genetic genealogy companies’ databases to establish the identity of unidentified human remains (“UHR”) and identify suspects using DNA collected at a crime scene. This “off-label” use of genetic genealogy, known as forensic genetic genealogy (“FGG”) or investigative generic genealogy, has been used to solve decades-old cold cases. FGG has also raised a red flag about the privacy of information stored in massive databases by internet-based companies

A report published in January 2024 by the Quattrone Center for the Fair Administration of Justice at the University of Pennsylvania’s Carey School of Law revealed that false positives in presumptive field test used in drug arrests are one of the most common, and possibly the most common, cause of wrongful arrests and convictions. The report, entitled “Guilty Until Proven Innocent: Field Drug Tests and Wrongful Convictions,” utilized a nationwide survey of law enforcement agencies and forensic drug labs to make its determinations.
Using data from the survey and national estimates of drug arrests, the report estimates the impact of (1) false positives in field drug tests on wrongful arrests, (2) racial inequity in arrests, (3) the subsequent prosecutions, and (4) criminal convictions. It reported that approximately 773,000 of the over 1.5 million annual U.S. drug arrests involve the use of color-based presumptive field tests. Although the exact error rate for the tests is unknown because they require a subjective determination by the arresting officer, available data suggest around 30,000 people are arrested in the U.S. each year due to false positives of the field tests.
“Presumptive field drug test kits are known to produce ...
