Beyond the security question, this person told me the mob action has been a psychological blow on the DC bureaucracy which didn’t think such an open expression of tangible disrespect for the government was possible. In other words, the capitol mob was a blow to their status, and Washingtonians believe the entire protest represents more than just anger at the election outcome: the disrespectful spirit of the day represents a real threat to their power going forward. This is one reason for the paranoia of Democrats at the moment, and they worry that more such protests are not only possible but likely. Part of the reason there is such fury on the left to run Trump out of office right away is that DC is genuinely afraid of him and his followers. Machiavelli might approve. Hence the calls to deploy national guard units in DC in large numbers for Inauguration next week.
