I don't doubt there was a conspiracy.
The question is one of attribution, and who was the object of that conspiracy.
After nearly half a decade of Russia, Russia, Russia, and other attacks on POTUS, there is no way that I would put orchestrating the whole show in order to attack, yet again.
That involves reductions in security, finally going so far (after agitating the crowd with pepper spray and tear gas) as to open the doors (when people in the crowd were stopping the agents provocateur from breaking windows). Funny how BLM guy was up front to capture murder on video (Ashli Babbit). How busloads of ANTIFAs were observed gearing up, and communications were intercepted to wear their MAGA stuff backwards so others would know them in the crowd (false flag). etc.
