I figure they have a LEA force with the Congress members. Another LEA group is probably trying to secure and clear the inner building. Another working outside inner perimeter of the Capital trying to keep some order. Then you have at least one or two outer perimeters. All this could be a couple hundred officers. They have Capital Police, Park Police, other local federal police, city, and state police, and the National Guard. The National Guard is a law enforcement filler taking over traffic control, or guard duty to free up law enforcement officers.
