Williams testified that he had experience in manufacturing or putting
together urea nitrate. He further testified that in manufacturing the urea
nitrate I actually used two formulas that were removed from one of the
blue manuals. (The blue manuals were manuals in Arabic and English for
home-made bomb-making.) Williams further testified that the formula
recommends that you mix the urea to the nitric acid in a one-to-one
range;. . .[i]t suggests that you mix by amount 60 parts of urea to 63 parts
nitric acid. He further testified, When I made a large quantity of urea
nitrate in the large plastic tubs, it was very heavy. On both direct and
cross examination, Williams used both the first person, singular pronoun
I and the first person, plural pronoun we to describe who made the urea
nitrate.
On cross-examination he testified:
Q. You reproduced an explosion using the same
chemicals and the formulas that was in the book?
A. Yes, I did.
Q. When did you do that?
A. In the early part of the spring and summer, we
started by making small batches of urea nitrate. And
then in August, I made approximately 1,300 pounds of
urea nitrate in Florida.
When asked whether he concocted a bomb with some of the urea seized
in the searches, Williams responded: I did. In the early tests in the
summer, I used some of the urea from Mallory [the location of one of the
searches] and made small one-pound bombs of urea nitrate and
detonated it.
Williams further testified to the production of urea nitrate at the Eglin Air
Force Base in Florida in August 1993. When asked why he used an
outdoor laboratory there, he stated, I didn't want to have any of the fumes
