If there are any documents of substance that were seized, photocopying them would do no good as a photocopy can not be introduced as evidence in any legal proceeding. If there were once classified documents aeized, they would have been declassified before or by being removed from the White House. When these declassified documents are finally returned, the media and the public will demand their release. Again President Trump will be forced to do what he wanted to do anyway and will suffer no consequences for doing so.
