I don't. The names are immaterial in looking for patterns. Credit Card companies routinely separate the names and PII from the credit and demographic data, crunch the numbers, and then only append the names back to those records they wish to market according to the scores generated (they have to make an offer of credit once they join name data and financial data, so that in a way is a similar scenario to mining call patterns and then getting names once you get a "hit").
As long as you can eventually link back, you can research the calling data and get cause from just the data. And my problem is, there is nothing remotely resembling probable cause in the entire Verizon database - instead, the government is looking at the data to determine probable cause, if they are data mining. If they are not data mining, then an expedited subpeona process would get them any specifica calling data they might need.
