The video released purpoted to be Trump purported to be conceding is fake and gay. Commentors at Anonymous Conservative and at Vox Populi have noted and pointed out defects, artifacts, and other flaws revealing the video to be a fake just like the last one taken in that location was. Furthermore, what was said--while clearly intended to be taken by the enemy, the Thralls in the media, as concession--was not a concession speech; those have a specific form to them, ending with "and so I end my campaign" and that was never said.
Remember what I said about how Trump is playing this: a deliberate invocation of the Passion. That's performing the role of a martyr, and the risk is that one actually gets martyred, a risk Trump accepted. This plays into the enemy's virulent hatred of Trump; these symbolism-obsessed occulists recognize the scheme and recoil at the power put upon them, and it is like a source of strength for Trump. Yes, they will attempt to openly assassinate him if they feel sufficiently threatened, and they will before the 20th. All of the shilling, etc. shows how rattled they are.
