Extra security or the National Guard that POTUS Trump authorized would be counter to the DNC plan for breach of the capital building.
The DNC already had their FIBs, ANTIFA and other assets in place to create a false flag operation.
A real capital cop whistleblower would be one who reveals who opened the secure fire doors and who ordered such.
Bingo!!!
and I think once the security started opening doors to let people in.... a lot of Trump supporters saw it as a “peaceful protest” that had been invited inside...only a very few did any damage..
