Or they are tourists caught in a park by the WH, in a storm of which violence they underestimated ….and tried to wait it out under some trees
The same thing happened to us years ago but we took refuge in the portal of the Library of Congress instead of under a tree. It was awesome hearing thunder in the mall.
All well-informed people know that being under a tree is the worse place to be. However, there are plenty of places to get out of the weather less than a block away. In fact, there is a bank steps away from the park, that you see on the back of the 10 dollar bill. 🙂
From the looks of the storm I saw on the video, that storm had been going on for sometime. At least that is what I deduced from the short clip.
