there is an interesting person assisting us, who is significant
Aaron wouldn't be interesting as help
The term he used was "interested party" to be more precise, if that makes any difference:
Taking into account everything he's teased so far, the most likely scenario seems to be that April has expressed willingness to consent to the release or already has, for three main reasons. First off it best fits the need for someone to run to the Spicer/Willmar area in person for her to sign pertinent paperwork that might have been impractical to coordinate remotely in her case, in stark contrast to something like delivering a written request or fee payment to a county office, which Hardin should have been allowed to FedEx straight from his office. Secondly she better fits the term "interested party" in that she has pre-existing legal rights pertaining to the footage, unlike EWU who just happen to be interested in seeing it like any other member of the public. Perhaps EWU could add some financial contribution and some relative air of legitimacy to a joint request to the county and as a co-plaintiff in any subsequent declaratory action, but their impact would stop there.
Thirdly and most importantly, it's very telling where he emphasized how he now knows that even in the "worst-case situation" he's going to get at least
some of what he wants and the "damage is already done" there no matter how hard Rekieta tries to stop it or undo it, and instead all that remains up in the air is whether he gets
all of what he wants in the best-case scenario. This likely alludes to a downside that hasn't been discussed much here or at least hasn't been widely accepted by the most optimistic here:
even if April gives her full consent and
even if she can't or won't enforceably rescind that consent, the county would be likely to redact any portion of the footage in which she does not personally appear, if not also redact portions in which she personally appears but the privacy interests of non-consenting parties are implicated, such as anything depicting the interior of the home. This problem could be easily overcome by her simply forking over a flash drive of the complete unredacted footage that would have been sent to her attorney in discovery from her own criminal case where there is no publicly filed protective order prohibiting that disclosure, but an NDA and/or some legal advice about any tort liability pertaining to the Rekietas' privacy interest must have hindered that option or else you'd think Null would already have gotten the footage that way, so for the time being county redactions limited to the scope of her consent can be expected.
Even after those redactions there would still be what April said in police questioning outside the home, which was damaging enough that Nick's omnibus motion prematurely sought to have it excluded from trial evidence, so it's still "significant" as stated and would technically be enough to win the bet with Ralph as well, but it would still take the written demand to the county and any subsequent litigation to obtain the vast majority of the footage that April's consent arguably cannot control.
That said, it's still at least
possible that all of the above could fit one or more of the sheriff's deputies consenting to release of whatever small portion of the footage their consent can control, which you'd think would go against department policy generally but might have warranted an exception here because of all the misconduct that Nick was dumb enough to allege or insinuate over the past year.
It's also at least
possible that Aaron could have been considered (or could still become) an "interested party" capable of "significant" assistance but in a different way: although he's not on the list of people who can consent to even partial release, a request for the footage could benefit from an affidavit from him regarding the effect of Nick's repeated public insinuations that Aaron may have planted the drugs, dosed the daughter, etc., which the footage would be needed to dispel. Moreover if it is true that he is preparing for any kind of legal action in the near future, then his attorney could conceivably use a subpoena to obtain at least some relevant portions of the footage, such as footage of the confiscated weapons and loose cartridge to the extent relevant to showing whether there's an objectively reasonable enough concern for physical safety to justify an HRO, or even footage of the drug search to the extent relevant to the low likelihood of his access to the drugs' location for purposes of showing harassing intent in an HRO case or showing a false statement in a defamation case, or even a broader portion of the footage to the extent relevant to defending himself against any defamation counterclaim from Nick that in any way implicates Aaron's past statements about the state of the home, etc. This still seems to be the absolute least likely possibility, however, for all the reasons previously discussed ITT about why he has held off from taking any legal action at all.
