I think there is some of the responsibility for this tragedy being over looked here:
Five minutes before the store was to open, the horde of unruly customers shattered the door, trampled through the half-dozen Wal-Mart employees who had desperately been trying to reinforce the doomed entryway, and proceeded to shop, according to police and eyewitnesses.
The employer and managers responsible for sending those under paid, no benefits workers to 'reinforce' should be criminally charged and fired. Walmart should also be investigated to see if this is standard practice to send employees into harm's way.
Common sense should tell you that if you have a pressing mob outside your front doors, you get people away from the doors and tell the crowd to get orderly or disperse ... or there will be no shopping period, we'll just turn out the lights and walk out the back door till the cops take care of the mob. This isn't just a story about the mob of shoppers being greedy and irresponsible, its about the business being that way too.
And not only that, but apparently there were police present? Why weren't they doing their jobs and calling in the riot police, ambulance, and demanding people get orderly or disperse?
There are all kinds of hands with blood on them with things like this. I hope some people who are running businesses read this: don't even try to do business in situations like this.
