Thatcher dragged herself into the Hillsborough tragedy by advising against publishing the criticisms of the police (quote lifted from the BBC website):

"What do we mean by 'welcoming the broad thrust of the report'? The broad thrust is devastating criticism of the police. Is that for us to welcome? Surely we welcome the thoroughness of the report and its recommendations - M.T."

Bear in mind Thatcher had turned the police into a tool for imposing her will on ordinary people, and this statement betrays her thinking in this matter.

There's another of her great legacies: Turning parts of the police force into paramilitary units. Making sure they are unaccountable for their actions, and are never, ever convicted even in such blindingly obvious cases such as the death of Ian Tomlinson. The force is a closed shop, institutionally corrupt and Thatcher was responsible for allowing this to happen, primarily during the miner's strike.
