It would appear that this is a very complex case. From the links Coronado provided it appears that the employees took their smocks of before chasing the woman down. Whether this was a done in order to avoid making Wal-Mart liable is another question. Regardless, Wal-Mart is handling this very carefully and aiding law enforcement in everyway in the investigation. I would say from my research of China, Wal-Mart will indeed be shouldered with some of this burden.
