I just re-read the article and it clearly says he shot FROM the roadway, not across like I said. Isn't that still illegal though? Maybe it depends on the state/province, but I think you can't pull over and fire off a round from the road.
Here in this graveyard it's still No Man's Land
The countless white crosses in mute witness stand
To man's blind indifference to his fellow man
And a whole generation who were butchered and damned.
