This guy has ‘I’m involved’ written all over him.
I say:
1) He knew Steve’s political views
2) Of course he knew about the purchases but
3) In light of (1) he probably knew something was coming ... soon
4) But Steve provided cash from whatever his source was (maybe he hit the lottery?) so he didn’t want to turn in the Golden Goose brother.
and somewhat to go down the old tinfoil road
5) He knew of brother Steve’s admiration of Antifa and/or ISIS. This one I’ll hold in the tinfoil category for now.
I suspect if old Steve would have been an extreme white nationalist that would have been our 2 seconds after the terrorist attack. Which makes me think he was left-aligned. Of course, I’ll also have to admit that’s tinfoil. At this point.
