朋友從屋頂摔下來發出巨響。John Danks離開電腦往外看
了看，覺得不嚴重就和他的朋友回去住處睡搞搞。並沒有
做出幫助關心朋友的舉動，更沒有叫救護車。現在他這
個傷勢不嚴重的朋友以後可能不能正常行走了...
Suddenly, Danks heard a "loud bang."
He looked away from his computer and saw his friend, 29-year-old Blake Papst, lying nearby on the wooden deck. Papst, who was standing on a roof above the deck with his brother, had fallen about 10 feet.
What followed immediately is in dispute but everyone is clear on one detail: An ambulance was not called. Instead, Danks and his two friends eventually went to sleep inside the condo, leaving Papst alone on the deck.
"He didn't act like he was very hurt," Danks later testified, according to court papers. "I mean, he almost acted like he got the wind knocked out of him more than anything."
But Papst was seriously injured; he has not walked again.
