It's interesting that you would use the example of phones. One of the things that I'm constantly hearing about in terms of the concern is the year's worth of metadata that is potentially going to be collected under this. I'm wondering two things. First, in the case of phone numbers, to the extent that a person has had a phone number for years and has a network of contacts in their phone, can you explain why you would need a year's worth of metadata to be able to get that kind of information?
