A positive GSR does not mean that an individual discharged a firearm, does it?
Well, as stated in my direct, the presence of barium and antimony is consistent with a ain proximity to a discharged firearm...
(Politely interrupting) a GSR test is a presumptive test, isn't it?
The test is very specific for the presence of the key ingredients...
Excuse me, a GSR test is a presumptive test, correct?
That depends upon what you mean when you use the term presumptive test
Have you not heard the term presumptive test in science?
Of course I have...
Then given your understanding of the term, is a GSR test a presumptive test?
Yes.
And this is because a positive GSR does not mean that a person fired a gun.

. Thank you. In fact, merely handling a gun that had been fired wouldlikely result in a positive GSR?
. Yes, depending on a number of variables.
. And that would be so even if that gun had been fired days earlier?
. Again, There are a number of factors that should be considered...
. In fact, if I take this weapon out of this plastic bag with my hands there isa good chance that I would flunk a GSR test.
. Probably.
. And then if we were to shake hands, you'd flunk the test too?
bjection to the word flunk

Doctor, is the Oxford Textbook of Pathology an authoritative text in thefield of forensic pathology?
What edition?
I have the 3rd.
I believe we are now on the 5th or 6th.
Any edition?
Well no, that text is a pathology text. It’s a medical school text, not aforensic text. In the field of forensic pathology I much prefer WernerSpitz’s MedicoLegal Investigation of Death.
