I thought i posted about this but must have got distracted
At the end of testimony from Forensic dude there is a fascinating sidebar about admissibility of some taped testimony.
I understood the debate to be as follows *
(* please not I am not a US law expert and have not worked in law since the 90s!!)
As I understood it, the State already introduced some Chase taped statements from Police interviews. e.g some of the 2010 interviews were played to the Court. This does not mean all tapes are admissible. For example, both sides appear to accept discussion of the lie detector test is not admissible.
The defence wish to play large sections of testimony from different interviews separated in time. So my guess is they mean to play not only 2010 interviews, but interviews after Chase's arrest in 2014.
Both the state and the Judge appear to accept that other sections of the 2010 interviews are admissible where they relate to the same question and issue.
So for example if Chase was answering a question in 2010 that the state played in evidence - the defence can play a different section of the same interview where Chase clarified his answer or addressed the same issue.
The defence appeared to be arguing that where Chase addressed the same issue, separated in time, (i.e, years later) then the subsequent answer is now admissible.
So this would mean if he gave an improved or different explanation in 2014 - the defence wants that to come in.
State argued that the admissibility only extends to answers in the same interview and the judge appeared to agree. However the judge invited the defence to submit authorities for their argument.
We don't know the result of that side bar.
My uneducated guess is that the defence want to use the arrest interviews to introduce Chase's version. And I guess this all has something to do with the 2010 interview being as a witness in the investigation whereas the 2014 interview is as a suspect.
