An 802 does not seem to jive with a deal forming for Wuterich would need to be present. Instead, he was outside during the break with his parents. The prosecution MAY (big maybe speculation) have used it to make an offer to defense council to present to Wuterich. If the latter, it signals the prosecution’s theory of the case is near total collapse.
More likely the 802 was to wrangle over the prosecution wishing to add a witness that was not on the list, perhaps a NCIS agent. Jones would hear arguments and consider it if the witness was to impeach testimony by a previous witness.
The prosecution is in no position to offer anything, IMO. They put on this ridiculous circus. Wisest thing they can do is fold their tent and slink out of town.
