Yes.  It's still "eyewitness" rather than "physical tests."  It's a 
description of the physical tests the cop performed, is what I was trying to 
say.

Yes.  Of course,  you have to evaluate the credibility of the witness. If 
one person says "I saw George leaving the building" and another says "George 
was with me in a different city all day", how do you resolve that 
scientifically?  That's what expert witnesses are for.  "Yes, this person 
*did* die because of a blow to the head, and not drowning, even though we 
found the victim floating in the lake." Is that a fact or an opinion?

When something only happens once, anecdote is all you have.
