Did they have a return flight back to UK from Canada? If true, why were they carrying $16k, and was it USD or CAD? Obviously Canada's alleged refusal to re-admit them needs an official statement (and explanation) too, why did WaPo not follow that up? Are their identities real? I guess only the courts will flush out anything even resembling the actual course of events in this post-truth era.
