(408 posts)I spent more than 30 years in the information business. Not the spying business - I worked to help insurance companies manage the data they collect about their insureds. Still, that experience left me with an understanding of the power of metadata. If it is all in a database, it is not that hard to get at it, and no, it does not require a human being to look at every record.
Do you know that a 'known' terrorist called a given number at a certain time of day on every other Sunday? You could search for everyone else who called that number, every one else who made a call at the same time, or anyone who called any one telephone number at the same time of day, two weeks apart. All just as easy. And very, very easy to make false interpretations of this data. Is it a terrorist cell? Or maybe just a local pizza parlor? Or maybe a terrorist cell at a local pizza parlor?
You may laugh, but I have seen business executives draw even sillier interpretations from their metadata.
