Matt Blaze is a fairly credible blogger, and a reputable cryptographer
who's done some very good work.  He also references the United States
Judiciary's 2010 Wiretap Report and Susan Landau's _Surveillance or
Security_.  If you're looking for references to back up his factual
claims, I'd suggest starting in either of those two.
