Well, I wouldn't have ever expected that "Skateboarder breaks windshield of McLaren car who didn't respect a stop sign" thread to still be going. Guess I sould never underestimate the ability of GAF to get blood out of a stone...
Driver not stopping at a full stop sign in a crowded residential area broke the law in a way that could have maimed or killed someone so he's the one most at fault.
Skateboard kid breaking the windshield out of spite is bad, no matter the carelessness of the driver. Maybe shouldn't have sped across a passage way too.
Really, what more is there to say ?
