RE: Jack Smith and the classified documents case. Smith made the right move to "wind down" the cases.
The logic is as follows:
1. By voluntarily winding down before Trump's second term, Smith removes Trump's ability to "Fire Jack Smith!!!", a punitive personal victory Trump has broadcasted countless times.
2. Secondly, and most importantly, there is nothing to prevent the Special Counsel from refiling charges after Trump leaves office. The case hasn't gone to trial, so there would be no double jeopardy if a future trial commenced, thus there are no constitutional reasons why the case couldn't be resumed in the future.
3. It respects the convention of not bringing charges against a sitting president.
