The pipe bombs found in DC on January 6th, were essentially the insurance policy. The FBI was supporting the need for a stoppage of the 2020 electoral certification session in congress. If the FBI could not manipulate the crowd into entering the Capitol Building, the "discovery" of the pipe bombs would have been used to shut down the certification session. Speaker Pelosi would then gain emergency power, switch to an emergency session upon return, and any effort to challenge the delegate affirmation would be nulled. The latter described action by Pelosi is exactly what happened.
