They suddenly swooped down on a junk dealer in Enterprise, Alabama and began to search every inch of his business including the pleasant job of digging up the septic tank.
I was watching this on TV with another grad student and we both laughed. It was so obvious listening to the owner that he was not the mad bomber that it was literally funny. Of course it turned out he had nothing to do with it and the only evidence was that the typewriter used to write some letter had once been in his junk.
Of course they have to check out all leads but this was ridiculous. The really do appear to be incompetent sometimes.
