Agreed. In fact, I'd think bleach would pretty much ruin upholstery and carpeting. I think I read somewhere that human blood stains will show up regardless of bleach or other cleaning materials--anyone have any more info on that? If that was Westerfield's purpose, I hope it fails.

I think you may be right about that, but not sure. While police dogs have great noses, there are things that can throw them off, and I would think bleach would surely be one of them. Had a friend at the FBI tell me that extremely cold weather can inhibit a tracking dog's sense of smell.
