They're trying to win an election right now, and all options are on the table. Arrests will not happen until after the election, if they happen at all. Maybe they called Biden's bluff on the laptop. Maybe it was nothing but dick pics and hookers, but does Joe and the crew really know that? They've probably done so much shit, they have no idea what could be on that. So, they call a lid on it now and lay low. That could have been the goal of the laptop all along. It's about the election for the highest office in the world right now. That's it.
