At about 20:30 in this periscope you'll see someone who appaers to be an employee of Comet (he looks familiar, someone please name him) and he says there was only one bullet fired, and he seems to almost immediately regret and tries to hold off the periscope that had been running for a long time already!

I tried to archive it (http://archive.is/YhoAU)), but it seems not to archive the video (I video'd the part from my screen, though) - somebody please archive the video.

Extra detail: in the video is Pizzagate Howie, who FOIA'd for pictures of the bullet holes and got an answer from DC Police that it wasn't ready for publication or something like that - I will try to find pictures of that and add later.
EDIT Here's his post about the FOIA request: https://twitter.com/PizzaGateHowie/status/845006061488746496
and here's the pictures:

Sorry for the mistake in the title, 'where' should of course be 'were'.
