Darhil Crooks, creative director at The Atlantic:
On January 7, 12 people were brutally murdered in Paris, including journalists, editors, and illustrators. Along with the brave staff of Charlie Hebdo, freedom of expression itself was attacked that day, and, in France and elsewhere, it remains under threat. We reached out to some of our contributors and asked them to articulate their reactions to this assault the best way they know how: through illustration. This gallery is dedicated to the people who lost their lives this week.
