Interesting questions Hank. The President of the United States was shot and you are asking if a metal fouling test is normally done on suspected weapons by police departments. Not police departments but the forensice science department within the court system is the typical agency that performs all tests to make sure the suspected weapon was used in the commission of the crime. The answer to your question is "yes" it is normally conducted and it was commonly used in forensics in 1963. Was it part of the SOP for Dallas' forensic science department? I don't know but it was in the FBI.

Killing the President was NOT a federal crime in 1963. The Dallas Police had jurisidiction. Ergo, I asked what was the standard for police depts in the US. So what's the problem? I dunno, but you apparently have a problem with my question. So enlighten me as to the issue.
What's the name of the test, and which standard forensics manuals mention it? (you skimmed over both of these).
Since when does the court system conduct any tests on weapons? Not sure where you're getting your info, but it's not true to the best of my knowledge.
The defense might call their own expert witnesses, as will the prosecutor, but there is no separate, impartial forensic science dept within the court system anywhere within the U.S.A that conducts those kinds of tests on weapons and makes those determinations.
To my knowledge.
That includes Dallas in 1963.
Who conducted the fingerprint search on Oswald's weapon? The Dallas Police Dept.
Who conducted the paraffin test? The DPD.
Who interviewed Oswald extensively? The DPD.
There is no "Forensic Science Dept" within the Dallas Court system. The closest I can come to what you're alleging is that the Dallas Crime Lab - a department of the Dallas Police Dept - was responsible for the analysis of evidence gathered in this case. J.C.Day was a member of the Dallas Crime Lab in 1963 and took responsibility for the evidence and conducted the tests on it he deemed necessary. Until they were ordered to turn it over to the FBI.
You say the FBI did this as Standard Operating Procedure in 1963, but offer no citation for this fact. Nor do you mention the name of the test, or cite any standard forensics books that say this test is standard. Nor did the FBI conduct any such test on the rifle once they had the weapon.
So, on the basis of what you allege above, I would say you are zero for six.
No federal jurisdiction over this case.
No evidence of court systems conducting tests.
No name of the test provided.
No standard forensics manual cited.
No evidence it was commonly used by the FBI or any police dept.
No evidence it was conducted in 1963.
So, again, could you name the test and provide a citation to a standard forensics manual that says that's a standard test for weapons suspected of being used in a shooting? A circa-1963 citation or prior would be great.
