There's another layer to this which I've been thinking about over the past few days, I think the angle of a color revolution tactic being pressed onto the US, perhaps to pressure Trump into compliance is perhaps becoming very evident.Pretti, it seems, has not been avoiding confrontation. This is still no reason to kill him as they did, at least as far as is known - hence undertrained. So, given Pretti's prior agitating (which is just what is now known), it seems eventually it was not going to work out well for him. The Valhalla VFT guy also adds that it is not know if he reached for his gun while on the ground, it didn't look like it, but who knows.
But I also think about how apt the US is for some of these things to work so well, I am not sure if I would put it past some individuals to seek glory by "suicide by cop" just to push their agenda even deeper. Like, the best thing that can happen to someone so self centered, in a group of people where everyone's doing the same thing, is to stand out by becoming a martyr The mental state of some of these folks needs to be taken into account as well.
Not to mention the ICE age, and the arctic POLAR VORTEX that is INVADING the US
