It is puzzling that the CCTV shown on Channel 4 showed no witnesses shocked near the gate at the time the incident was unfolding. It did show two women walking past, but they were a long way from the gates, they didn't stop, they didn't look and showed no signs of being shocked.
And now footage from another angle apparently (because we have not seen it) shows two women.
How can footage of the same scene have people appearing and disappearing? Why has the new footage only just come to light after all this time? Should someone be prosecuted for withholding vital evidence?
