The irony is that "the people inside the DOJ with responsibility for the matter" appointed someone, Mueller, who has even more conflicts of interest than they had.
It's a hard thing to say, but I think that Mueller's real mission is to locate and destroy evidence of criminal wrongdoing by Democrats. The question I have is whether Sessions and Rosenstein gave Mueller this sub rosa assignment, or whether Mueller is on a frolic.
The only problem there is that "destroying evidence" is increasingly difficult in the modern world where there are digital copies of almost everything of importance anyway.
Think of Hillary Clinton's illegal e-mail server. She could delete every file, "bleach" the server, and launch it into the sun on a space mission to ensure that everything was destroyed, but it still wouldn't do anything to deal with the problem that every e-mail has both a sender AND a recipient ... and passes through multiple mail servers between one and the other.
