CYBERSECURITY, PRIVACY and TECHNOLOGY

An email privacy bill requiring federal agencies to obtain a warrant before searching Americans’ digital communications was unanimously passed by the House yesterday.

The encryption status quo is “unacceptable,” say Sens.  Richard Burr (R, NC) and Dianne Feinstein (D, Calif), chairman and vice chairman, respectively, of the Senate Select Committee on Intelligence, who are circulating a proposal in the Senate designed to ensure that tech companies and individuals give the “appropriate technical assistance” on judicial request to law enforcement agencies.

Be cautious in judging the 28-pages when they become available, advises Carol Giacomo, echoing the warning of the leaders of the independent commission that investigated the 9/11 attacks and produced the report of which the 28-pages is the remaining redacted portion. They issued a statement last week warning future readers that the pages contain allegations based mainly on “raw, unvetted material” which has not had “the benefit of follow-up investigation.” [New York Times]

“Put bluntly, the United States is relying on an authorization to fight those responsible for Sept. 11 to wage war against groups that had nothing to do with those attacks and, in some cases, didn’t even exist at the time.” Just Security’s Jennifer Daskal argues that the Obama administration’s expansive interpretation of the 2001 AUMF “empowers future presidents in dangerous ways.” [New York Times]
