I speculated that the acquittal of Scott Warren for giving aid to the people crossing the desert regions on the US southern border was possibly a case of jury nullification, the process by which juries acquit someone who is guilty on the facts because they feel that the law is unjust or should not have been applied in that case. Ryan Devereaux of The Intercept says that what happened with Warren was not jury nullification but the government being unable to make the case.
To put this another way: there is no indication that this was a case of jury nullification. The government lost all on its own by putting on a case that was unconvincing to the jurors.
