An Indiana University student has released an audio recording disclosing the degree to which Sprint has been cooperating with law enforcement requests.

“Christopher Soghoian, a graduate student at Indiana University’s School of Informatics and Computing, has made public an audio recording of Sprint/Nextel's Electronic Surveillance Manager describing how his company has provided GPS location data about its wireless customers to law enforcement over 8 million times,” writes Ars Technica’s Jon Stokes.

“That's potentially millions of Sprint/Nextel customers who not only were probably unaware that their wireless provider even had an Electronic Surveillance Department, but who certainly did not know that law enforcement [officers] could log into a special Sprint Web portal and, without ever having to demonstrate probable cause to a judge, gain access to geolocation logs detailing where they've been and where they are,” Stokes adds.
