Yes, I downloaded the video and analyzed it, he had a rifle in a case with a shoulder sling. I saw it too.
If you watch a slowed down version of the video, when he is about to descend from the roof, he turns his back to the camera that is recording him, he’s wearing the backpack and holding the rifle, to me it’s clear as day.
I agree this whole thing stinks, but this is one conspiracy that can be quashed immediately.
