There's a good possibility that Saddam was traced by Tempest sensing, airborne or mundane.

I wonder if you can trace DNA in sewers back to the source, esp. in an inbred locale? (Peter? PCR with Saddam specific primers?) Or did he just dig a cat-hole instead of using the infrastructure? You can trace industrial contamination up sewer lines back to the source. How about the cells we shed? Just theoretically. Papers fnord says someone used to the good life narced, couldn't handle a jail cell.
