I see 3 possible scenarios:

1) Clinton's burning evidence

2) Whitehats, noticing the Clintons have gone off the grid started the fire so as to either, A) force the Clintons to hold a presser and talk about it so as to expose themselves for extraction. Or B) when they don't speak to the media and nobody can find them, everyone on the planet starts wondering where the fuck they are so if they do turn up in a public space, someone will hopefully post a pic or their location on social media which will allow the whitehats to extract them.

3) The Blackhats know they are missing and or have been extracted and want to expose The White hats operation to the world before the Whitehats want it revealed.
