“No it isn’t. Springing it in the middle of a hearing is not disclosing evidence to the defense. You like being on the wrong side of things, don’t you?”
OBVIOUSLY you missed that day in law school where they discussed evidentiary hearings.
The defense didn’t know about it so they couldn’t argue the merits of the evidence. That’s not disclosure, that’s a cheap ambush, by a cheap prosecutor.
You know about that kind of tactic, you cheered for that for two years in Texas.
