That would be unbelievably stupid. It's not like in DOJ anyone cares if she "did the right thing", they'll put her in the slammer all the same. Not even Hillary Clinton would get off scot free after something like this.
A jury (with nullification power), in principal, might (as might the electorate who choose Presidents who have pardon and clemency power); if you aren't going to flee to avoid capture and aren't confident of your ability to evade the counterintelligence services in the long term, compromising your ability in the short term to improve the optics of the event may not be completely irrational, even if it is far from guaranteed to pay off.
I've not only been on juries, but studied them. Nullification is a thing. It's quite rare and unlikely in the specific circumstance at issue, but that's already factored into the discussion in the grandparent post.
