In the 1982 movie The Verdict (and, possibly, in the original novel as well), the respondent's lawyer cites "McGee v State of Indiana, United States 131.2" (at 1:57:10):
The admission of a duplicate document in preference to an existing original must presuppose the possibility of alteration so must be disallowed.
Is that case a complete fiction, or is it just that I can't find it?
Did the cited admissibility rule ever exist?
Would something like what happened in the movie happen today i.e. where a witness produces a copy of a document they made, and testifies that the original of it (already adduced to evidence) was tampered with after making the copy, would the copy still be inadmissible?
