I'd imagine that in the real-life version of this commercial, it's just some under-paid lackey sitting inside a cubical who grabs your file from his inbox and calls you 6 times, before submitting a form with your phone number and address to an IRS Agent who arrives with an arrest warrant.
I think they save the GPS and computer surveillance for the big boys. You know, local terrorist groups and middle-eastern countries sitting on barrels of oil (whoops, I mean WMDs).
