Likely because people with clear consciences react by saying "huh, there's nothing to see; go for it, I'll be right here."

One irony that has escaped some folks: You've got a group of people who are up in arms (possibly literally) over their leader being investigated and raided -- and indeed the witch hunt turned up a coven of sensitive documents that shouldn't have been there -- and their reaction is to say that "when we get into power again" they are going to conduct their own investigations and raids in retaliation. Not even claiming they suspect a specific offense, they clearly state it's in retaliation.

The most hilarious one though was MGT, who wants to abolish the FBI. Be careful what you wish for, lady, they keep tabs on the foreign terrorists as well as the homegrown ones such as your fanbase.
