If you see them marching, get close up pictures of their faces. They can be identified from just their eyes.
The local WV television news did not cover this event, I never heard it mentioned. Maybe I missed it but I doubt it.
I would have gone down and looked for the usual rental truck and cars with the license plates covered, and take some pictures of the agents. Let them try and arrest a 93 year old, that would have made the local news. LOL
