The retail giant Wal-Mart has reached a settlement to avoid charges for the death of a worker crushed by a stampede of shoppers last December. Thirty-four-year-old Jdimytai Damour was killed after a crowd of 2,000 broke down store doors and ran him over shortly before the store’s opening. Wal-Mart will pay nearly $2 million and pledge to improve safety at its New York stores.
