Absolutely the wrong way to look at it.
Biden has followed the constitution to the letter in the separation of powers clause. He has kept his nose well clear of the DoJ. In fact, I don't think he's publicly commented on the ongoing investigations, other than to acknowledge their existence. Had this situation been reversed, there is absolutely NO WAY Trump wouldn't be able to keep his nose out.
It is Trump and the Republican party who need to tread VERY carefully. Biden needs to be prepared to react accordingly in order to protect national and domestic security, but that is it. He is completely hands off, and rightly so.
