* Publicly available information that anyone can obtain by request, purchase, or observation.
* Includes but is not limited to: news/ blog articles, PDF reports/other docs found on the internet, visual and audio recordings, satellite imagery, internet archives, websites and databases & social media posts and user-generated material such as videos and photos posted on the web.
* Methodological challenges of using open source information in legal cases, such as: reliability, availability, and security – difficulty in verifying exact location, date, time & identifying the individual (expertise required) à markers of authenticity noted in Katanga and Ngudjolo
* Risk of information being removed from platforms before being preserved & security of eyewitnesses and those who gathered the information first-hand, or even bystanders visible in a photo or video
