Unless I looked at a different recording, I don’t see that someone got all of it. The video I saw showed policemen tending to a person on the ground, so it was after the main event. No video of the shooting itself.
There are lots of people roaming around in DC, and most have cell phones, so I don’t find anything surprising or suspicious about the recording.
