This video has been proven to be at least partially faked and edited, check out this Corbett Report, watch the whole thing before jumping to conclusions and downvoting me, please. It appears as though some of the audio has been dubbed over in post production.

I'm not a shill who goes around "debunking" most conspiracy theories, because most of them are true, but disinformation like this is dangerous and can discredit us, so it's important to be skeptical.
