KevHead writes "Speaking at a conference of international police chiefs, FBI Director Robert Mueller called for strict data retention guidelines for US ISPs. Echoing DHS head Michael Cherthoff's assertion that the Internet was enabling terrorists to telecommute to work, Mueller went further and said that the US needs stricter data retention guidelines. '"All too often, we find that before we can catch these offenders, Internet service providers have unwittingly deleted the very records that would help us identify these offenders and protect future victims," Mueller said. The solution? Forcing ISPs to retain data for set periods of time.' If that happens, how long before the MPAA and RIAA start asking to take a peek at the data too, as they have in Europe?"
