The FBI has had Hunter's laptop for some time and haven't done anything with it. Taking Rudy's copy would raise questions as to why nothing is being done with it.
Did it ever occur to you that perhaps there is nothing that CAN be done with it? Did it ever occur to you that there may not have been enough incriminating content that would rise to the level of an indictment? Did it ever occur to you that because of the manner by which the laptop was obtained a federal judge might rule it inadmissible ? Obviously not. Trouble is, you cluckers get so caught up in your right wing conspiracy theories that you can no longer think for yourselves. When one has been thoroughly debunked you simply move onto another.
