"Corrupt motive" is an extraordinarily vague and open-ended term that can be expanded or contracted at the whim of zealous or politically motivated prosecutors. What constitutes a corrupt motive will often depend on the political bias of the accuser. I know because I am currently being accused of being corruptly motivated in making my argument against charging President Trump with obstruction of justice. They assume a corrupt motive. So beware of creating precedents that lie around like loaded weapons in the hands of overzealous or politically motivated prosecutors.
