CALEA

Kevin Drum of Mother Jones appears to be unaware of CALEA.

Wiki:

The Communications Assistance for Law Enforcement Act (CALEA) is a United States wiretapping law passed in 1994, during the presidency of Bill Clinton (Pub. L. No. 103-414, 108 Stat. 4279, codified at 47 USC 1001-1010). In its own words, the purpose of CALEA is:

To amend title 18, United States Code, to make clear a telecommunications carrier's duty to cooperate in the interception of communications for Law Enforcement purposes, and for other purposes.

CALEA's purpose is to enhance the ability of law enforcement and intelligence agencies to conduct electronic surveillance by requiring that telecommunications carriers and manufacturers of telecommunications equipment modify and design their equipment, facilities, and services to ensure that they have built-in surveillance capabilities, allowing federal agencies to monitor all telephone, broadband internet, and VoIP traffic in real-time......In the years since CALEA was passed it has been greatly expanded to include all VoIP and broadband internet traffic.From 2004 to 2007 there was a 62 percent growth in the number of wiretaps performed under CALEA -- and more than 3,000 percent growth in interception of internet data such as email.
