That was a fascinating case as far as PC controversies go. People react differently in such situations - some with instinctive fear. Ever walked up to the wrong house after getting bad directions? There are any number of possibilities that could explain noises outside. I wouldn't open the door late at night unless I were expecting someone who had already telephoned. I would look out the window first. If I wasn't satisfied at that point, I would call the cops. The kids were skinnydipping in the backyard pool in the Rowan case, right? A prank.
In this case it seems like he was waiting for the kid, caught him walking across the grass, shot him with a shotgun (slug) from a distance of some 20 or 30 feet (as described in a post above) and then walked the distance and fired point blank again (a second time!). That's not "self-defense" in any book.
If the kid was postrate in the street, that's not a good crime scene for the shooter.

That's not "self-defense" in any book. I'm not familiar with crime scenes, but when this was shown on the news, there were 20 small, numbered cards standing up in various places. Wouldn't the police be marking gun casings or something? Maybe the guy only HIT the kid twice but shot at him 20 times?
