The second flag was thrown by the back judge Midfield 40 yards downfield 7 seconds after the first flag was thrown.
Neither was in any position to make that call, worse no one on earth can possibly judge depth from that distance. There is no way either of them should have ever thrown that flag unless they felt invested in a penalty for some reason. Corrupt
The replay booth is usually filled with a wannabe who lives in fear of making the cool guys on the field mad. They hate to overturn penalties. They will ocasional y overturn a play but a penalty? It is almost like people have deeply held positions against fake Christmas trees and Artificial surfaces. It is a belief system and they are not going to go against it.
