The most questionable thing is definitely that man pointing towards the video. I used to be a lifeguard and when an emergency happens you are so focused on resolving the issue in front of you that most everything else becomes background noise. Pools are busy in the summer but that's only a fraction of people compared to the marathon.

Just how that guy noticed the camera when caring for someone literally missing their legs is beyond me. The lady approaching the situation, noticing the camera, and TURNS AWAY FROM THE WOUNDED tells me there was no pressing injury that had to be taken care of. That, and the caption mentioning paramedics were denied access to help. Any real life threatening situation would have had paramedics at the scene ASAP and would have gotten them to the hospital ASAP. It just feels so forced and coordinated how they cleared the area yet left a few injured people for show.

I just stumbled upon this today. I basically gave up reading about this, Sandy Hook, and Brussels, because as you say, the evidence is sparse and basically conjecture. Yes, there are very, very suspicious things that have happened, but what're we gonna do about it? They hold all the cards and information.

This video was annoying to watch. Make your point a little quicker next time. And sure okay shit loads of fbi. Doesn't make it a hoax. But yes suspicious indeed.
