Limitations Of The NAA
Claim: Nobody can say what the bulk homogeneity of bullet CE 399 is.
Response: True, because there is no such thing as bulk homogeneity in WCC/MC
lead. There are zones of higher and lower concentrations of antimony.
Claim: Elemental analysis will never resolve how many bullets were
fired at the president.
Response: True, but we have never said it would. We speak only of the
number of bullets that hit.
Claim: NAA cannot differentiate WCC bullets from SMI from Norma from
Peters (presumably all soft leads).
Response: Maybe true, but irrelevant. The Sturdivan statistical treatment
takes care of this.
Claim: A standard deviation of 45% in Sb over a bullet will prevent us
from matching fragments from it.
Response: False. It all depends where the variations are found.
Claim: If a fragment has the same concentration of antimony as the tip
of one bullet and the base of another bullet, you can't tell which it came from.
Response: True, but irrelevant to the JFK scenario.
