Masked Man wearing earpiece was caught on video breaking a Capitol window, Not added to FBI's list

The DOJ just gave a January 6th protestor a ten-year sentence for breaking a Capitol window.

Suspiciously, a masked man wearing an earpiece was also caught on video breaking a Capitol window but has never been added to the FBI's most wanted list, arrested, or charged.

In the video, the unidentified man, dressed like a government agent, encourages a journalist to break the window, saying, "Why don't you guys open up the rest of it?"

The journalist responds, "Because I think that would probably be illegal."

The masked man acknowledges the illegality by saying, "Well, I know," but then suspiciously breaks the window himself.

Shortly after realizing he is being recorded, the masked man quickly drops the window and violently shoves another man, awkwardly blaming him for breaking the window.

As the DOJ sentences one Jan 6th protestor to ten years for breaking a Capitol window, the question arises:

Why isn't the FBI interested in identifying this masked man wearing an earpiece who was caught on video breaking a Capitol window?
