CLKD - I don't think there was a way out for the people who were killed, they were crushed before they fully got into the stadium. There was no way to escape or get onto the pitch when fans were pushing from behind to get into the ground on time.
I think it's the families themselves who want the inquest, they were not happy with what was decided on at the first one. Also, I think the lawyers won't be unhappy at the fees they will accumulate during the coming months.
