Unlocking the Black Box: Challenging the Use of Secret Algorithms and Technologies in Criminal Cases

Increasingly, technology is being used in the criminal legal system to identify DNA samples, assess risk factors in release decisions, match images in face recognition technology and even determine where or who the police should be patrolling and investigating. From probabilistic genotyping to “risk assessment” software, the recent explosion of emerging technologies has transformed almost every aspect of the criminal legal system. Increasing amounts of data and evidence are being interrogated and generated using software systems that are kept from defense teams, the courts, and the general public. The assertion of “trade secrets” by the companies who develop these tools deprive defense lawyers of access to information on how the software was constructed and the opportunity to assess its accuracy, credibility and reliability. How can criminal defense attorneys understand and confront the limitations of software-based evidence and machine learning algorithms in criminal proceedings? 

Challenging Digital Evidence Obtained through RoundUp and Torrential Downpour in Criminal Cases



Prosecutors are employing novel and unproven surveillance software to investigate peer-to-peer file-sharing networks for criminal activity, seeking to link suspicious activity with internet IP addresses and subscriber information. The software suite, known as “RoundUp,” includes applications designed to monitor popular file-sharing platforms such as BitTorrent (e.g., “Torrential Downpour”) to conduct highly-intrusive digital surveillance. How can defense lawyers recognize the use of RoundUp or similar programs in a criminal case?

Using Police Technologies to Uncover Law Enforcement Misconduct in Criminal Cases


Since 2017, the Baltimore Public Defender’s Office has called over 2,000 convictions into question related to police misconduct. In one instance, a Baltimore Police Department body-worn camera appeared to show an officer planting drugs at the scene of an arrest. As law enforcement agencies are increasingly using surveillance tools and forensic technologies to identify and arrest suspects in criminal investigations, defense attorneys are faced with the challenge of both defending their clients and holding police accountable for misconduct and abuse. How can criminal defense attorneys turn police technologies on police departments in criminal proceedings?
