Civil liberties groups are ramping up efforts to challenge the use of Google search data by law enforcement agencies to aid in criminal investigations. The practice is facing increased scrutiny across the United States as privacy concerns continue to grow.
The latest case that has sparked controversy occurred in Pennsylvania in 2016 when a woman was raped. In an attempt to gather information, the police obtained a search warrant from Alphabet's Google, requesting data on users who had searched for the victim's name or address in the week leading up to the attack. Google provided the IP address of a user who had searched for the victim's address shortly before the incident. This breakthrough enabled the police to discover a corrections officer who was subsequently arrested and convicted.
However, the Electronic Frontier Foundation, along with the National Association of Criminal Defense Lawyers (NACDL) and its Pennsylvania chapter, recently filed a court document arguing that the investigative technique known as keyword search warrants is excessively broad and poses a threat to the privacy rights of innocent individuals. These organizations believe that keyword search warrants function as digital dragnets, granting the government permission to search through private information.
Michael Price, the Litigation Director of NACDL's Fourth Amendment Center, stated, "Keyword search warrants are digital dragnets giving the government permission to rummage through our most private information, and the Pennsylvania Supreme Court should find them unconstitutional." As of now, there are only a few known instances of keyword search warrants being used, but their potential implications have drawn national attention.
In the wake of the US Supreme Court's decision to overturn the right to abortion, concerns about keyword search warrants and geofence warrants have intensified. Privacy advocates caution that these investigative techniques could be exploited to prosecute women obtaining abortions in states where it is illegal. Recently, the Colorado Supreme Court ruled that evidence obtained through a keyword search warrant could be used in a murder trial. This ruling raised concerns that law enforcement agencies might increasingly employ this controversial technique.
Nevertheless, the Colorado Supreme Court emphasized that its decision was based on the specific circumstances of the case and refrained from making a broader statement about the use of Google's search data. This has provided hope for civil liberties groups fighting against keyword search warrants in Pennsylvania. The Electronic Frontier Foundation's Surveillance Litigation Director, Andrew Crocker, believes that the change in Google's policy regarding geofence warrants makes it even more crucial for courts to assess the constitutionality of keyword search warrants, especially as law enforcement agencies continue to seek new investigative tools.
In December, Google decided to halt its practice of responding to geofence warrants. This decision came shortly after a Bloomberg Businessweek investigation revealed how law enforcement agencies across the country were increasingly acquiring location and search data from Google, even for nonviolent cases and for individuals unrelated to the crimes. Crocker explains that this policy change by Google amplifies the importance of examining the constitutionality of keyword search warrants, as they may gain popularity among law enforcement agencies searching for new ways to gather evidence.
The battle over the use of Google search data in criminal cases is ongoing, with civil liberties advocates pushing for stricter limitations to protect individual privacy rights. The outcome of this legal challenge in Pennsylvania could have significant implications for future investigative practices and the balance between law enforcement needs and individual freedoms.
