If I see a stainless steel particle in the garbage that comes with the sample, then that tells me something about the kind of containers it was processed in. It's not just about the main organism used in an attack - it's about all the other stuff that comes with it. If you look through that stuff you can find a lot of clues that can lead you back to the attacker.

When I'm writing a song, it's just me and the songwriters. Then when the song is done, there are publishers that hear it, then people in my management, then my wife and my boys and my friends, and if they're all lovin' it, it's kind of withstanding all the criticism I need.
