One small thing I noticed was how the witness statement differed from the guy who was shot.

Seems the pickup started away, but Harbachuck caught up to it when it stopped at the stop sign. Harbachuck then started banging on the passenger side window. And yes, this is after the woman (driver) had gotten out and back in.

Yes, the shooting was still over the top. But I get this impression that had Harbachuck had a gun there might have been shots from his direction first.
