1:04:00
not knowing any
of the background at all
of what was going on.
1:04:05
They wanted somebody
from the laboratory to say,
1:04:07
"Yes, we analyzed these samples.
Yes, we produced this report
on the analysis."
1:04:12
And that's
what I was there to do.
1:04:23
I don't think
the Leuchter results
have any meaning.
1:04:28
There's nothing
in any of our data...
1:04:31
that says those surfaces
were exposed or not.
1:04:38
Even after I got off the stand,
I didn't know where
the samples came from.
1:04:43
I didn't know
which samples were which.
1:04:46
And it was only at lunch
that I found out really
what the case involved.
1:04:52
Hindsight being 20-20,
1:04:55
the test was not
the correct one to have
been used for the analysis.
1:05:03
He presented us
with rock samples...
1:05:06
anywhere from
the size of your thumb up to
half the size of your fist.
1:05:11
We broke 'em up
with a hammer...
1:05:13
so that we could get
a sub-sample,
1:05:16
placed it in a flask,
1:05:19
add concentrated
sulfuric acid.
1:05:23
And it undergoes
a reaction.
1:05:26
It produces
a red-colored solution.
1:05:30
It is the intensity
of this red color...
1:05:34
that we can relate
with cyanide concentration.
1:05:45
And you have to look
at what happens to cyanide...
1:05:48
when it reacts with a wall.
1:05:52
Where does it go?
How far does it go?
1:05:58
Cyanide
is a surface reaction.
