What a horrible story. A Wal-Mart employee was killed at a Long Island store — crushed by the onslaught of a mad crowd of shoppers on so-called Black Friday.

Roughly 2,000 people gathered outside the Wal-Mart’s doors in the predawn darkness.

Chanting “push the doors in,” the crowd pressed against the glass as the clock ticked down to the 5 a.m. opening.

Sensing catastrophe, nervous employees formed a human chain inside the entrance to slow down the mass of shoppers.

It didn’t work.
