We need to convince them it would be so easy for someone to destroy this "dangerous conspiracy": Just ask POTUS on camera to confirm it.
I was thinking along the same lines. Those 2 videos being posted by Q along with the hashtag and the outright accusation of evil, seems very much a dog whistle to draw out a response from HRC, at which point the media will get it's marching orders to go confront POTUS on Q's "hateful rhetoric".
Force the question.
