This is my presentation at the fOSSa 2013 conference held in Lille, France last November, titled Open Source Intelligence: What Connects the Walsall Anarchists, Nazi Pigeons and Ben Affleck? This was intended as a fun introduction to and demonstration of my work, and was very well received. The conference was also notable because it where I first got to meet James Corbett face to face, after well over three years of collaborating online. James recorded and edited this video, so direct your thanks at him if you particularly enjoy this. I just did the standing and talking. And the pictures of Nazi Pigeons. I thoroughly enjoyed doing this, though it doesn't look like it for the first few minutes, so thanks are also due to Stephane Ribas and Patrick Guillaud for the invitation.
