Why was Mary Surratt not photographed after her arrest?

[RJNorton]

I don't think she was arrested, questioned, etc. Theodore Roscoe wrote, "But do not arrest the society woman who had consorted with him (Booth) in Washington drawingrooms. Do not impound this amourette who seated the killer near Lincoln at the Inaugural. Never breathe the name of Booth's betrothed. She is privileged, beyond the law, sacrosanct. She is the daughter of a United States Senator!....Senator Hale whisked his daughter to Spain soon after the Lincoln tragedy. There the veils that concealed her face were even more impenetrable that those offered by the War Department."

Philip Van Doren Stern wrote that Miss Hale "was the only one near Booth who did not have to pay a public penalty for having been associated with him."
