Never, in the history of trial testimony, is fiber evidence testified to as a "match" by the witness. Lawyers can and will use the term, though.
Wait and see what Dusek says in closing. He used the term "match" in his opening, I believe.
and that is the scince of fiber analysis - They are never determined to be an exact "match". They are looked at for similarities. The only way to proclaim and "exact match" as far as I have ever read is to analyze the compounds and dyes in the fibers, but to do so destroys the evidence.
