What do I do if I screw up an investigation during a workplace investigation?

What do you do if you screw up an investigation? I'd be lying if I said I've never screwed anything up. I don't think I've ever screwed up a whole investigation, I've done some things that I've had to redo. And I think that's just it, part of doing an investigation, part of doing a neutral and unbiased thorough investigation is that sometimes it's also the humanness of the investigator that comes through and you just got to fess up with it. If you are not transparent and accountable, I don't know how anybody's going to respect the work product you produce an investigation as being transparent and responsible either. And so there have been times that I've had to do investigative work like re-interview or fix a report on my own dime, and that was the right thing to do, and it stunk. But it was the right thing to do. I did it a lot more when I was a new investigator, a baby investigator, than I ever do now. But I guess I got to be an old investigator because I did the right thing when I was a young investigator.
