I am pretty confident that these are Feds and someone will likely give them better training on how to blend in when trying to enact false flag operations in the future.
However, can you imagine how embarrassed and stupid these guys feel today if they were actual MAGA bros trying to support the Jan 6th political prisoners and everyone is making fun of them?
I could be wrong, but most people who support Trump already expect to be treated badly in the media. They may have mentally prepared themselves for the possibility. But it's highly unlikely they are innocent MAGA types, or they would more likely have been blurring their looks with low-hanging hats, loose clothing, face masks, etc.
