Correct me if I am wrong. Doesn't the defense have access to these types of evidence? Is part of the defense's job to check and verify evidence?
Unless I'm hearing this all wrong, I seem to get an implication that the evidence is false, or mis-interpreted. Then, the defense misses the falsification, and/or the mis-interpretation?
Then, the good folks on FR find it? Too bad the good folks at FR didn't get the information to Feldman, in time for him to bring it up on cross-examination.
Or maybe the defense did their job, checked the evidence, found no falsification or mis-interpretation, so didn't bring it up on cross-examination. (Meaning good folks at FR are wrong about this)
In any event, it is probably too late, to re-introduce the topic in sur-rebuttal.
