When the Hillsborough tragedy occurred, there was an attempt to portray the victims as pickpockets, drunks and generally anti-social beings who were at least partially to blame for what befell them.
Some of the people who perished in the fire, and possibly others who did not, were/are illegal immigrants. But, as someone else said, all these mutterings detract from the real scandal of what happened in that high rise. What I think is really distasteful is the linking of people's possible illegal status to the subject of terrorism.
