While the United States continues to debate metadata collection conducted in secret by the National Security Agency, the European Union has been openly collecting the same sort of data for eight years.
In the wake of terrorist attacks in Madrid (2004) and London (2005), the European Union passed a directive in 2006 requiring that all telecommunications providers retain all kinds of telephone and Internet metadata for at least six months and provide it to law enforcement upon request.
According to a ruling handed down Tuesday by the European Court of Justice, that directive is now invalid.
