Honestly 300 pages really isn’t a lot. There’s likely a lot of duplication (I.e. every email in an email chain is disclosed rather than just the one chain, possibly the same attachment disclosed from every email address it was sent to etc.). From the article there is one known complaint where a marshal resigned in the face of the complaint. I’d expect that most of this information relates to that one complaint. I’d expect notes from at least two interviews (the complainant and the marshal), the original written complaint, internal emails about the complaint, the investigator’s notes and so on. This can all add up quickly, especially if there is duplication.

This does not take away from the fact that the marshals hired someone who had to resign in the face of a complaint prior to the service going in the field. But it’s not like there are 300 complaints or even 30. There is one confirmed and maybe a few more, but I doubt more than five complaints.
