New Details Show Broader NSA Surveillance Reach. The Wall Street Journal reports that the NSA "has the capacity to reach roughly 75% of all U.S. Internet traffic" with its surveillance systems, more than had previously been reported. "In some cases, it retains the written content of emails sent between citizens." The Journal also reports that during the Winter Olympics in 2002, the NSA "monitored the content of all email and text communications in the Salt Lake City area" for "a period of less than six months."

US doesn't know what Snowden took, sources say. According to NBC, the National Security Agency is still trying to figure out which documents Ed Snowden leaked to Glenn Greenwald. "Officials, including NSA Director Keith Alexander, have assured the public that the government knows the scope of the damage, but two separate sources briefed on the matter told NBC News that the NSA has been unable to determine how many documents he took and what they are." The agency is said to be "overwhelmed trying to assess the damage."

Verizon exec mocks double standard on net neutrality. "Randal Milch, Verizon's vice president of public policy and general counsel, argued on Tuesday that federal regulators would crack down on his company if it engaged in the same business practices as CBS," reports the Hill. "CBS is currently blocking its Internet videos for Time Warner Cable subscribers. The network began blocking the content after it and Time Warner were unable to reach an agreement for carrying CBS stations in certain markets." The FCC's open Internet rules prohibit ISPs from blocking users' access to content but do not apply to content producers such as CBS.

IP Cloaking Violates Computer Fraud and Abuse Act, Judge Rules. The ruling "marks the first time a court has offered this interpretation of a highly controversial law that affords both criminal and civil penalties," Wired says. "The legal issue concerns 3Taps, a site that was scraping classified ads from Craigslist and republishing them without consent. Craigslist sent the San Francisco aggregator a cease-and-desist letter and blocked 3Taps’ IP addresses from accessing the site. After circumventing the IP blockade, 3Taps continued scraping and was sued under the CFAA."

Kagan, youngest justice, says her esteemed colleagues aren’t the most tech-savvy. The Associated Press reports on Kagan's Tuesday remarks at Brown University. "The justices are not necessarily the most technologically sophisticated people,” she said. While the clerks communicate by email, “the court hasn’t really 'gotten to' email." She says the court's communications habits haven't changed since she was a clerk there in 1987.
