People, who as a result of their actions, cause the untimely death of other people, who did not deserve to suffer an untimeley death. They also cause the untimely sanctioning of other innocent people, not associated with them, by some stange obscure default.
Murderers - People who wore the red shirts of Liverpool and attended a certain football match, in which 39 Italian supporters died, at their hands. These same people never appeared as remorsefull over the incident, yet want us all to remember the tragic events of Hillsborough, every other day. As a result of their actions they barred everyone from competative football. Murdering Twats.
