Bottom line:
whether they (the protesters or rioters) were present at the rally or not, they all traveled to the Capitol because they were encouraged, or influenced, by the President (he knew exactly what he was doing). I watched the whole broadcast “live”, as it happened
Why wouldn’t the president (“Mr. Common Sense”) at least try to call them back once the violence erupted? Hours passed before he would make any response, apparently he watched the whole situation unfold back at the White House (once again, he knew exactly what he was doing).
The Capitol is a highly secured institution, you can’t just casually enter voluntarily. You would have to be a fool to breach security, rush and attack the police. Then expect not to be shot, breaking through the final door leading into the main chamber (where the actual vote is confirmed). I wouldn’t.
However, the Capitol Police were physically attacked and overwhelmed by the rioters, and were ultimately allowed entry.
