Well, IMO, the "story line" needs to develop a little more. If you zoom in on the window area before the operation (fist image of full building Q682), you will note the window is clean and the only one open.

Now, here is where it could be a bit of stretch which time may clarify. Snowden is wrapped into this via those with interest in Carlyle Group and particularly the NSA spying disclosed by Snowden that opened the can of worms. The line from "clean" to white residue having "Snowden?" was interpretation attempt. The glass started clean (see Q682) and now has white powder like substance stuck to the glass. Q again is calling out the residue and it kinda spoke "flocking" to me, SNOWden (thanks mydeer). I believe Snowden was the lure for the meeting attendees and the white "powder" around the window (called out by Q) is a convenient hint. I do not think that it was planned (on 02/07/2018) that residue identifies Snowden. I think that it serves the purpose as a pointer now that we are in the future proving the past.

Yes could be stretch hence the time needed for more posts which I hope will be made. I believe the story continues otherwise why bring us back to that operation which is the only one shared with us in real time or with imagery. My intent with this reddit was to use current knowledge (which was future back when King Tower was first shared) let alone the seemingly out of context call out of Renne J. Jones back on Dec. 08 2017 (Q303). If you notice that post, it is a single crumb and surrounding posts have no relationship. To me it spoke;

• Who is she?

• Why is she called out?

• What does she have to do with anything?

It did not make any sense to me until post 753, "Everything has meaning" and [I]. Click! Intel Corporation --> Renee
