She was arrested 3 weeks ago. If it was a plant, what purpose did it serve to wait to release the news until now? Given where the world's focus was 3 weeks ago, it'd have served Russia better to make the arrest public then as an attempt to deflect from the Valieva story. The news being released now, in the midst of the Ukranian war and the State Dept advising, just yesterday, all Americans to leave Russia, makes me feel it's a sympathy ploy on the part of her attorneys.
Maybe I'm being too cynical again.
