DIGITAL FOOTPRINTS AND CRIMINAL LIABILITY: LEGAL AND CRIMINOLOGICAL PERSPECTIVES.

Abstract

This paper examines how social media both facilitates criminal behaviour and transforms criminal investigation, with attention to legal and criminological implications for Nigeria and comparative international frameworks. It argues that platforms such as Facebook, Instagram, X, and TikTok create opportunities for offences including fraud, identity theft, cyberstalking, hate speech, grooming, organized-crime coordination, and misinformation by increasing accessibility, anonymity, transnational reach, rapid dissemination, and weakened guardianship, effects explained through social learning, routine-activity, strain, and online disinhibition theories. Simultaneously, social media furnishes investigators with valuable intelligence, geolocation data, multimedia evidence, and undercover access to networks, but the effective use of these resources is constrained by evidentiary authenticity rules, privacy and data-protection concerns, jurisdictional limits, and uneven institutional capacity within Nigeria‘s police, EFCC, NITDA, and related agencies. After surveying domestic statutes (notably the Cybercrime Act 2015, Evidence Act 2011, Communications Act 2003, ACJA, and the Terrorism Act 2022) and relevant international instruments, the paper recommends stronger data-protection enforcement, clear admissibility standards for digital evidence, judicial oversight of surveillance, enhanced investigator training and forensic capacity, and improved international cooperation to balance public safety with constitutional rights. These reforms aim to align investigative practice with legal safeguards while mitigating social media‘s criminogenic effects.
