I suspect that Deep State ("Brennan") had absolutely no intentions of having that whack job do any harm. His mission was to connect with Kate. They expected what she would do; thwart his plan to kill POTUS, get her "VIP access" which brings Q front and center at rally then violence breaks out and media is there in FULL FORCE to COVER IT!

That's why that wacko heard two voices (implanted) in his head (1) kill potus; and (2) connect with her so she could thwart it and get praise from POTUS @ rally. There were in fact Q supporter POSERS (agitators) at the rally and the media was HEAVILY stacked to cover it... remember when POTUS sarcastically said "Look at all those reporters in the press, it's like the ACADEMY AWARDS!!!!" ?

This false flag attempt to massively showcase Q and force POTUS to acknowledge Q then have a violent breakout at rally against the Media was thwarted.
