Bloomberg News reports that, as expected, today "[t]he US Senate approved a four-year extension of provisions in the USA Patriot Act allowing law enforcement to track suspected terrorists with roving wiretaps. ... The measure goes to the House for final passage before being sent to President Barack Obama for his signature. The surveillance powers would be extended until June 1, 2015." The story mentions that the Patriot Act powers this approval includes would extend "to so-called 'lone wolf' suspects who aren't affiliated with any terrorist group."
