But as with anything the real reasons will take effort to parse, but this from Reuters goes some way to explain it:
According to British media law star Mark Stephens of Finers Stephens Innocent (whom The Times of London has dubbed "Mr Media"), Rupert Murdoch's soon-to-be shuttered tabloid may not be obliged to retain documents that could be relevant to civil and criminal claims against the newspaper—even in cases that are already underway.
If News of the World is to be liquidated, Stephens told Reuters, it "is a stroke of genius—perhaps evil genius."
