PROBLEM #2 - When were they in Harlem?

"The reportage makes it plain that two girls were taken from their mother when she was defenceless against preventing that from happening."
PROBLEM #3 - "defenceless". The mother gave consent. The question (unasked by the beloved BBC) was about what that consent entailed. Were the rights explained? We don't know because the beloved BBC failed to ask.

"They were then treated in an oppressive fashion." By their definition. You weren't there, neither was I. Was it really oppressive?
