Sometimes it's totally possible to be there for every part of a situation and still not know how you got into it. One minute, everything's fine and the next, there are suddenly cop cars everywhere, wild animals on the loose, and people are yelling things that might only make sense to them.
But you can bet that while you're trying to find a way out of the madness, somebody is already recording the carnage. And when this type of stuff goes down, that's actually a good thing because that might be the only way we'll ever make sense of it.
So whatever is happening to these people, the point is that somebody got it on camera.
