Well, as more of us are riding with video (I now have front and rear facing high def video, and people like this are the reason more of us are equipping ourselves like this), hopefully we'll get dangerous idiots like this locked away for assault with a deadly weapon and maybe some of their massive trucks sold at auction, and we might start making some progress.

As for myself, I would never say the words "HAVE a friend" like that. It would be past tense. Hell, I'd probably turn him in myself. I'd turn in family that admitted to doing that, let alone a friend. If he's serious, the guy is a psychopath and WILL KILL SOMEONE EVENTUALLY, and IMO you would be complicit in anything that happens to someone after hearing such an admission.
