Sounds like she had a fairly typical experience here in China (from her account of the attack on ESPN):
"[the attacker] had one hand on his hip, the other waving the knife in the air. I asked my teammates later to translate what he was saying.They told me he was yelling, "I'm going to kill you!" ... I remember looking to the front of the bus because it seemed too much time had passed -- four or five minutes. Where was everybody? The bus driver was still in his seat, and a man who seemed to be a security guard was standing on the stairs. Both appeared to be frozen, maybe unsure how to help."
