> Were any proven to be brought INTO the capitol?

The fact that capitol police were completely overwhelmed by the insurrectionists, preventing arrests and searches in the Capitol presents rather strong proof issues with “inside the Capitol” (pretty much everything charged as “inside the Capitol” is based primarily on video evidence from the insurrectionists themselves, who were not shy about announcing their purpose.)

I would also note that the crowd having overwhelmed the security in the building, the armed insurrectionists outside the building on the Capitol grounds were more usefully positioned to interfere with any relief effort.
