Hi OP. Just letting you know that there's a rule against discussing current events in this sub: anything within 20 years is considered "current". While the Hillsborough disaster did occur more than 20 years ago (15 April 1989 for you non- Premier League football fans out there), it's possible that the answer to your question will involve more recent events. You might try x-posting in /r/LiverpoolFC or /r/soccer for a more thorough discussion.

Meanwhile, I'll leave this up here in case the relevant events really did happen prior to 1994.
