Question: When Adaline gets arrested is it because she is she is suspected of being a communist or something else entirely?

Chosen answer: It was because she had used so many fake I.D. the F.B.I. had become suspicious, possibly believing she was involved in some type of criminal activity, which is often why people assume different identities.

No, that can't be right because she doesn't start using fake names until AFTER the incident with the FBI. She was still using her normal name, Adeline, when the FBI grabbed her. The implication of the story is that they grabbed her because she didn't age and they wanted to use her as a lab rat.
