A wide diversity of views and pluralistic ownership of news media provide a free and independent press. There are several restraints, however, which could limit general freedom if projected beyond the present limited issues. Nazi propaganda and statements endorsing Nazism or neo-Nazism are illegal. Similarly, Germany polices the Internet to block access to obscene, violent, or "dangerous" material. The government has brought charges against service providers (ISPs) and individual users. In April, police raided 103 homes in an investigation into the sale of neo-Nazi music on the Internet.
