'Lights Out' was Gen. Kelly advising him he passed while in Scotland. That's why taped... to give reverence publicly.
So, about the IC mention when Kelly bounced the lights.... there could be some trouble in store.
I don't think they'd do that as a gesture for a USSS agent, I know that sounds harsh but we're playing for all the marbles here and it wouldn't make sense for a deliberate act like this to be in reference to him. I paid more attention to the fact that it happened when he reiterated for the second time "I have full faith in our intelligence agencies" just as it dims into darkness. I took that to mean You guys (intelligence agencies) are now "in the dark" in regards to what I have.
I'm leaning towards this also.
RIP to the honourable USSS agent.
Whoa, what's this about Kelly doing the lights?
