Stormningen av Kapitolium (2021-01-06)

Confidence that the D.C. and federal police plus National Guard can handle the situation is based partly on experience. The D.C. police force here has managed crowd control with more than 100,000 demonstrators in the past, one official said. To manage the crowds, control points will be established near the main march sites with police officers joined by the guard.

A final reason for confidence is that officials anticipate that left-wing counterprotesters from antifa and Black Lives Matter will mostly stay off the streets. That would lessen the likelihood of confrontations that could escalate into bloodshed and serious disorder, which might encourage Trump to invoke the Insurrection Act.
