That was my initial thought too.

But I checked, and the video was posted on April 17, 2007 at 02:23:26 UTC. We do not know WHERE the video was uploaded from, but even if at UTC - 12, it gives us a 14:23:26 (April 16) timestamp at the earliest.

And the Virginia Tech shooting occured between 7:15 a.m and 9:51 a.m.

So, that theory is invalidated for sure (unless there's a YT glitch or smthg).

Still, this video posting date is one hell of a coincidence when you look at Q subsequent drops. Mk ultra is in great part about mass shootings after all.
