I don’t know who designed them but on http://www.lineto.com/The+Designers/Stephan+M%C3%BCller/Work/Terrorism/ you can see others designed by Stephan Müller, with a font you can download: http://www.lineto.com/The+Designers/Stephan+M%C3%BCller/Work/Terrorism/D...

If you are looking for the original designers i think it’s time for infiltration!

One of my first jobs early in my career was to redraw several hundred hate crime/terrorist organization symbols/logos/etc. for the Anti-Defamation League.

They can be found here: http://adl.org/hate_symbols/default_graphics.asp

I finding myself getting deeply depressed while working on this project. Glad it’s over! Many of them, graphically, are quite interesting.

Good question Satya! Never thought about the fact that terrorist organisations like so many other organisations need identities. Don’t think you’re gonna find the designers though. They are probably hiding in some cave with an old 486 processor at their disposal;o)
