David Cameron's plans must not rely on web filtering.
The Pirate Party, which campaigns for web freedom, was unsatisfied with Cameron's ideas. Party leader Loz Kaye said that the policies were confused: "With search engine blocks and web filters, there is no foolproof 100 percent block solution. It will always be too much or not enough. This is utterly technologically illiterate. It can not possibly work in the way that Cameron wants."
