There was a threat to POTUS, identified by the US Secret Service, and action taken to prevent anything bad from happening at the rally. Comms dark meaning, no Q posts just prior to the rally about the threat, and/or Q signs/posters taken away from attendees? Thus sending a message to whomever was behind the threat - WE KNOW WHO YOU ARE. Someone trying to cause violence and frame Qanon. Deep state / Mockingbird?
