The title is from this USA Today article. On 7-17-18, as Trump was expressing “faith in the intel community”, the lights went out for a few seconds (see the video below). To me it was rather a “key moment” when the lights went out, right after Trump praising the intel community. I had read somewhere that it was General Flynn who turned out the lights, but not I cannot find a link, so I’m not completely sure about that.
In any event, it may be saying, “We are turning the lights our on the “dark intel community”. Later I found these images which may connect to prior Q posts: https://imgur.com/xzbuUcx; https://imgur.com/a/RFL4Qtd; I’ve linked the first one in the image at upper left.
There appears to be an attempt to connect this post from 6-17-18, to the “dark to light” event of 7-17-18. Honestly, I’m not sure exactly what’s going on here, but I’m putting it out there. Perhaps some others can figure the whole thing out.
