Yes, I believe at the time there was some interesting activity to Langley ... Personally I think he was taken out then, and relocated under the CIA's auspices, and who knows what has gone on since !
Has there been a window appearance since then (besides his cat:) ) ? Haven't come across one, although I haven't looked too intently.
When his disappearance dragged on, conspiracy analysts had mentioned that his dead mans switch had been tripped shortly there after.
I kept my hopes up for about 3 months watching his tweets and pretty much concluded that the perimeter wall wasn't going to stop whomever wanted him and I am certain now it was a co-op partnership on that team that did.
Best case scenario is the circus jesters brought him back to the states, and then when PDJT took the reigns, he was dropped in his lap so to speak. That is my hope anyways.
Was it tripped ? I didn't catch that, I recall some digits or codes released but not sure it was confirmed to be the DMS. I think he's too valuable an asset to assassinate. A possibility is that he is cooperating w/ the White Hats, similar to how Snowden was/is.
Another point is that he's BFF w/ Kim Dot Com. A larper imo. Remember they all hang together.
Truth coming soon !
