More info on the Antifa instigator, Jeremiah Elliot, who aided in the death of Lee Kelter. In an earlier post here, you can see Elliot trying to stage a fight with people leaving the conservative gathering before the shooting.
Elliot's past was dug up and it happens he helped "lead" Antifa rioters during their siege of the Aurora Police building.
The name of the tactic behind the shooting is being dubbed "the change up".
TLDR: Basically the threat matrix has changed. Politically backed killings by Antifa, to sow public fear and distrust, are now in play. Also, the media/press are not your friends. In many cases they are actively aiding and abetting these people. 9News is also owned my a giant media conglomerate named TENGA, said media conglomerate is also running the investigative journalism for this incident.

Note the sympathetic way the reporter leads the interview as well as Elliot's demeanor.
