This is a terrible thing, both for its happening, and for the fact that it is nothing new. Large crowds need crowd control, end of story. The Who concert in Cincy back in 1979 should have driven that point home.
The people who trampled this poor man are responsible for his death, and I hope (but am not holding my breath) that there will be arrests and prosecutions of those involved.
IMHO, though, Wal-Mart also deserves some blame for creating an unsafe situation in the first place. For a store of that size, with an event like Black Friday, having extra security on hand or other procedures in place to ensure safety is (or should be) the cost of doing business.
Prayers for the friends and family of this poor guy.
I have been in crowds like this before like general admission for the USC-Notre Dame game and seen kids fall etc.
It doesn't take an Einstien to see that they were totally unprepared even to the point of building integrity.
The brain-dead crowd took the hinges off the doors and stormed the store. What law enforcement personnel or Wal-mart could have stopped them? A metal portion of one door was crumpled like an accordian. Wal-mart is not responsible for people behaving like Neaderthals after the hunt.
