Secret Service Tap? (Score 1)

So, why did the Secret Service have a tap on this guy's line? Or was the tap on Digimarc?

Short apparently couldn't stop thinking about it, as he broke down and called Digimarc for support--twice--a couple of days later asking whether he would be able to obtain printer drivers. Secret Service Special Agent John Bush told IDG that he recognized Short's voice on the recording from another, unrelated investigation and that the phone number that Short had provided matched up to another identity theft case. Here's another tip for thieves: don't use your regular phone number for all of your crimes. Get a business line or something.
