Three Tests Proved Oswald's Innocence
« on: April 30, 2018, 02:14:40 AM »
    Test 1:  Spectrographic Analysis
                 Oswald's paraffin casts were subjected to two analyses. Spectrographic analysis , the method normally used by the police, showed evidence of barium and antimony on Oswald's hands , but not on his cheek .

    Test 2:   Neutron Activation Analysis on Oswald
                 Spectrographic analysis was considered sufficiently reliable for criminal investigations, but in this case a more incisive test was also used. Neutron activation analysis, which is capable of identifying the presence of substances in quantities much to small to be captured by spectrographic analysis, also showed no incriminating quantities of residues on Oswald's cheek. The result was reported in an internal Warren Commission memo: " At best, the analysis shows that Oswald may have fired a pistol, although this is by no means certain. ... There is no basis for concluding that he also fired a rifle."

    Test 3:   Controlled Neutron Activation Analysis

                  In order to check the validity of the neutron activation analysis of Oswald's paraffin casts, a controlled test was made. Seven marksmen fired a rifle of the same type as that found on the sixth floor. The standard paraffin test was administered, and the paraffin casts were subjected to neutron activation analysis. All seven subjects showed substantial amounts of barium and antimony on their hands and more impotantly , on their cheeks.

The absence of significant quantities of residues on Oswald's cheek meant that he almost certainly had not fired a rifle that day.

In 1963: The Paraffin test was known to be essentially worthless. It was prone to false positives and false negatives. It was used to trick naive suspects into giving a confession.

However, you seem to believe in the effectiveness of the paraffin test. Does that mean that you accept that Lee Harvey Oswald fired "a gun" on Friday 22 November 1963? You know... the Smith & Wesson revolver with which he shot Office JD Tippit. The discarded bullet hulls from the gun being found near the crime scene were matched to the weapon to the exclusion of all others.

If not: How do you think Oswald got "nitrates" on his hands on Friday 22 November 1963?

In other words: his Smith & Wesson revolver. You know: the one with which he tried to shoot Officer N.M. McDonald in the Texas Theater.

"Because oxidizing agents in common use by the public may produce
positive reactions we may say that the Dermal Nitrate Test is specific
for nitrates but non-specific for gunpowder or gunpowder residues"


"Another weakness of the test is that any oxidizing agent, such as
any nitrate, will produce a positive reaction
".

The following non-incriminating
nitrates may be found on the hands of the following persons:
Substance Handled Persons in Contact with Substance
Bleaching agents Launderers and housewives
Chemicals and pharmaceuticals Chemists, engravers, matchworkers,
pharmacists, photographers etc.

Cosmetics Women
Explosives Miners, construction workers
Fertilizers Farmers, gardeners
Firecrackers Boys in particular and people in general
Foodstuffs, certain types Public in general
Tobacco Smokers (potential cancer victims)
Urine People in general
Leguminous plants Farmers and gardeners

As you said - the paraffin test was worthless.

The lame LN excuse for this is that he scrubbed his face when he was at the rooming house.

Yes

Matt, The test of his hands proof that he not fired a rifle within 24 hours.

The Carcano rifle was hot immediately after Lee Harvey Oswald "fired" the three shots that killed President Kennedy. However the rifle was not "fried".

His (Oswald's) hands got nitrates on them when he used his Smith & Wesson revolver to murder Office JD Tippit.
