There's the issue of violating a "restricted area" you didn't consider. Yes, IF congress was in session, it would be open. But, was congress in session as a result of threats (ie. breaking and entering)? I believe the capital police shut it down as a result of this. I tend to think as a result of video evidence, there was a honey trap set here. When you have Antifa being filmed breaking and entering, it sure makes a great opportunity for a lot of innocent people to get caught up in the fray. I believe this was the intent all along. So, naturally the provocateur Antifa that were filmed breaking and entering means nothing to the narrative as long as they advanced that it was 'all Trump supporters'. Obviously, this wasn't the case because 99.9% were always outside participating in a peaceful rally. This is identical to the Charlotteville FF.
