These Niburu/Planet X people are kooks and frauds.
You can't assume they are honest or that they haven't manipulated the audio or video. They're complete liars about everything.
And they've taken time out from their usual kooking about Niburu and Planet X and used their expertise to produce just one Vegas shooting video, the one you posted.
They're kooks. It's a kookarama. They live to kook. They are trying to branch out from kooking about Niburu/Planet X into kooking about the Vegas massacre. But it is still just kookery. Because they are raging kooks.
This video doesn't really rate its own thread, though I do like VxH's Klingon bird of prey.
He's focusing on the sound of the bullets - claiming the shots are local.
Completely ignores the associated pattern of report that follows the bullet pattern.
The report is sub-sonic. The bullets are traveling faster than the speed of sound. That's why there are TWO distinct and separate groups of sound events associated with the same shots.
