We actually know who he is. His name's Kevin Seefried from Delaware (by the way, can you think of a reason why a man travelling from Delaware to DC might have a few creases in his flag?). He has been flying a confederate flag outside his home for most of his life. He has a prior conviction of a misdemeanor for terroristic threats in the 90's. He was identified after bragging to a co-worker that this was him in the photo.
This. Is. Cut and dry. This is not a false flag thing. He is exactly what he looks like in the photo and he got caught for it, and he's up in front of a federal court next week and he deserves it.
