It might have gone unnoticed in a previous post, but this is important enough to reblog.
Kevin at Patronus Analytical specializes in tracking, improving and mitigating the security hazards aid organisations face.
Recently, he started tracking all security incidents reported in the press in one overview, and mapping them out (see the 2008 and the 2009 map of incidents).
This is the best overview anyone can get of security incidents involving aid workers.
Highly recommended and once again: a fine job, Kevin!
