Putting aside the fact that Evans is being an utter **** over Heysel and that Liverpool fans were primarily responsible for what happened there regardless of what he claims, IMO the fences did play a role in what happened at Hillsborough. In 1981 Tottenham played Wolves in the FA Cup semi-final there and Spurs fans were housed in the Leppings Lane end. There was a crush following Tottenham's opening goal which lead to 38 Spurs fans suffering injuries. There easily could've been fatalities due to the fences but the police - to their credit, unlike 8 years later - helped alleviate the situation by opening the gates at the front to allow Spurs fans to escape, many of whom were then allowed to sit around the perimeter of the pitch for the rest of the match.
