Maybe so, but they didn't drag you in, you entered of your own accord. Why?
Yes. A mob is an unruly thing. If you watched the live streams of the riots this past year you would see the Antifa types taking specific actions (setting fires, encouraging burning of cars, supplying things needed to further the riot). So a crowd might have shown up to do a March but are then used as the pretext to riot.
Most there today were to peaceful protest as we had with many Tea Party events. A mix of antifa and some far right folks took it as a chance to do this. The police backed up abs let them in and the media response is coordinated. They got selfies and FBI investigating and Trump got the blame.
Don’t expect the actions to be ignored like the leftists that have occupied and rioted. Dems will seek and destroy those that entered the Capitol.
I thought essentially no damage was done to the historic paintings, statues, and other items. Damage done was to doors, the tragic death, and the expected media spin of it all.
