The funny thing is, that there are at least six people with black nylon backpacks in the picture. So obviously an entire swarm of terrorists is depicted...

I feel the same way. This thing is ridiculous, someone could name the person in the image, and media will go after them. But in the end they will end up innocent and their life in ruins. As much as this may seem like a good idea, 4chan or the internet should away from pointing fingers at random people with backups.

Thomas Crowne affair.

But: yes.

Crowdsourcing may be useful to develop leads. But LEO really should take it from there.

Seriously what is going on here? Why are they the only people standing there not helping who aren't holding a camera, holding a head wound or old?

They're trying to find out if there are other devices or if there are bombers still around.

So if they are feds then someone literally planted this bomb right under their noses.
