The Capitol was the focal point of the protest due to the location and in this case the perceived injustice of the election. When almost half the voting population thinks there is something wrong with the election, maybe its time to listen to those people. If anything I think the hivemind and unemployed young people showing frustration was the spark that ignited what happened yesterday.
I am not trying to justify it as good or bad, but it was not a coup by a long shot and you cant haphazardly label it as such.
