Many of those interrogated were never charged and have not been identified. That suggests that the court, despite its secrecy, was prepared to reveal its mission to innocent students as it attempted to identify those more closely involved. As the court proceeded, it had increasing amounts of information to use to question witnesses and challenge their statements. Some were called back for follow-up questioning. Nor did the court restrict itself to people with a Harvard affiliation. At least two witnesses lacking a Harvard connection responded to its summons, though it is unclear whether they participated voluntarily or under some threat. One was Ned Courtney, a Boston boy whose name was mentioned in testimony as the "main annoyance" for his frequent telephone calls to Perkins. Another was Harry Dreyfus, who was connected through his relationship with Cyril Wilcox and his employment at the Café Dreyfus, a known homosexual gathering place.
