FBI embarrassed again

FBI Finds Explosives in Nichols' Home :
"'But I'm still suspicious that it could be something planted there. The house was empty for several years and if somebody wanted to put something there to incriminate Terry they had plenty of time to have done it,' [Nichols' attorney Brian] Hermanson said."

I don't share attorney Hermanson's suspicion of a frame-up. But, this new discovery certainly shows the FBI in rather bad light. In all their searching did they use either bomb-sniffing dogs, electronic chemical detectors or metal detectors in this crawl space?
