Death-by-feet, or some ludicrous charge

The Washington Post has an article about the Wal-Mart disaster:

Police were reviewing video from surveillance cameras in an attempt to identify who trampled to death a Wal-Mart worker after a crowd of holiday shoppers burst through the doors at a suburban store and knocked him down. Criminal charges were possible, but identifying individual shoppers in the video from Friday may prove difficult, said Detective Lieutenant Michael Fleming, a Nassau County police spokesman.
Other workers were trampled as they tried to rescue the man, and customers stepped over him and became irate when officials said the store was closing because of the death, police and witnesses said. At least four other people, including a woman who was eight months pregnant, were taken to hospitals for observation or minor injuries. The store in Valley Stream on Long Island closed for several hours before reopening.
Police said about 2,000 people were gathered outside the Wal-Mart doors before its 5 a.m. opening at a mall about 20 miles east of Manhattan. The impatient crowd knocked the employee, identified by police as Jdimytai Damour, to the ground as he opened the doors.
