Why data protection is necessary.
From Wired News: What They (Don't) Know About You. When Richard Smith got his FBI file, he learned a lot of interesting things about himself. He found out that he had died in 1976 and that he may have previously been married to a woman named Mary. He also discovered that he may be known as "Ricky Smith" or "Rickie Smith" -- aliases he shares with a couple of convicts doing hard time in Texas. En fin, Smith -- who is the chief technology officer of the Privacy Foundation -- found that his FBI file contained more errors than correct data.
