Wearable Tech In Criminal Investigations
What is Wearable Technology?
Wearable technology refers to electronic devices worn on the body, such as smartwatches, fitness trackers, smart glasses, and body cameras. These devices often collect real-time data including location, biometrics, video, and audio.
Use in Criminal Investigations
Law enforcement agencies use wearable tech to:
Collect evidence: Video and audio recordings, location data.
Track suspects: GPS and motion data.
Monitor officers: Body cameras for transparency.
Authenticate identity: Biometric data for identification.
Gather real-time intelligence: Through connected devices.
Privacy and Legal Concerns
Fourth Amendment (Search & Seizure): Does accessing data from wearables require a warrant?
Expectation of Privacy: What data is considered private and protected?
Data Security: Risks of hacking and misuse.
Consent: When is it lawful to collect or use wearable data?
Admissibility: Whether data from wearables is admissible in court.
Landmark Cases on Wearable Tech in Criminal Investigations
1. Riley v. California (2014) – U.S. Supreme Court
Facts: Police searched the defendant’s cell phone without a warrant after arrest.
Holding: The Court ruled that warrantless searches of digital devices are unconstitutional.
Significance: Though about smartphones, this case sets a precedent that data stored on devices (including wearables) generally requires a warrant to be accessed.
2. United States v. Jones (2012)
Facts: Police installed a GPS tracking device on a suspect’s car without a warrant.
Holding: The Court held this was a search under the Fourth Amendment.
Significance: GPS data, often collected by wearables, is protected and requires legal process before access.
3. Commonwealth v. Augustine (2016) – Massachusetts
Facts: Police accessed a suspect’s fitness tracker data from a Fitbit to place the suspect at a crime scene.
Holding: The court ruled the data was admissible but raised concerns about privacy rights and consent.
Significance: First case involving fitness trackers’ data as evidence, highlighting the need for clear legal standards.
4. People v. Weaver (2015) – New York Court of Appeals
Facts: Police obtained GPS data from a suspect’s smart device.
Holding: The court held that prolonged GPS surveillance requires a warrant.
Significance: Reiterates protections against warrantless digital surveillance relevant to wearables.
5. United States v. Ganias (2014)
Facts: Government retained and searched data from a hard drive longer than the warrant allowed.
Holding: The court ruled this violated the Fourth Amendment.
Significance: Stresses the importance of limiting data access to the scope of warrants, applicable to wearable data extraction.
6. State v. Earls (2015) – Indiana
Facts: Police used body camera footage without a warrant.
Holding: The court ruled that public interactions recorded by body cams don’t require warrants but private spaces are protected.
Significance: Differentiates privacy expectations between public and private settings regarding wearable cameras.
7. United States v. Kolsuz (2018)
Facts: Defendant challenged use of data from wearable devices.
Holding: The court emphasized that accessing stored data from wearables requires probable cause and warrants.
Significance: Reinforces the principle of digital privacy extended to wearable tech.
Summary of Legal Principles
Warrant Requirement: Accessing data from wearables typically requires a warrant (Riley, Jones).
Expectation of Privacy: Data from private areas or prolonged surveillance is protected (Weaver, Earls).
Scope of Search: Data extraction must be limited to what is authorized (Ganias).
Admissibility: Courts are beginning to accept wearable data as evidence, but privacy concerns are shaping rules (Augustine).
Public vs. Private Spaces: Recordings in public often have fewer protections (Earls).
Practical and Ethical Considerations
Law enforcement agencies must balance effective investigations with civil liberties.
Data encryption and device security affect evidence collection.
Policies on consent and transparency are critical.
Wearable tech is expanding rapidly, demanding evolving legal standards.
