`Even before the gates opened, the atmosphere turned surly, with people yelling at police officers who were trying to keep the crowd civil.
When the first off-duty police officers arrived at 6:10 a.m., they called for more officers to assist with security, Police Chief Henry W. Stanley said.
Ultimately, up to 45 officers were there, as were fire and rescue personnel.
The gates opened at 6:54 a.m., and the stampede — literally — was on. The first crush occurred at the main gate to RIR and the second occurred at the entrance to the building where the 4-year-old iBooks were being sold.’
