Barbara Marcolini, a visual investigator with Amnesty International's Evidence Lab, joined us for May’s episode of Show & Tell.
Before joining Amnesty, Barbara was a founding member of the Visual Investigations team at The New York Times, where she won five News & Documentary Emmy Awards and was a Pulitzer Prize finalist.
You can watch the episode above or on our YouTube channel.
Barbara walked us through her 2025 visual investigation into Israeli military operations in southern Lebanon. The videos that she found and geolocated, together with reporting from the ground, led Amnesty to conclude that “Israeli troops deliberately left a trail of destruction as they moved through southern Lebanon. Among the structures affected are homes, mosques, cemeteries, roads, parks and football pitches.”
In our conversation we discussed what it’s like to work as a journalist within a human rights organization – including the reporting, fact-checking, and legal review process.
Barbara also told us about her favorite Google dork (keyword site:t.me), and why Google Lens is the best reverse image search tool, even if it sometimes tries to sell her clothes.
