Patrick O'Neill writes: The debate over surveillance hit the 2016 race for the White House again on Sunday when Republican presidential candidate Marco Rubio said he wants to add to American surveillance programs, many of which were created after 9/11. He invoked a recent shooting of a Philadelphia police officer by a man who allegedly pledged allegiance to the Islamic State. "This the kind of threat we now face in this country," Rubio said. "We need additional tools for intelligence." Rubio also addressed the NSA leaks that led to this debate: "Edward Snowden is a traitor. He took our intelligence information and gave it to the Chinese and gave it to the Russians. We cannot afford to have a commander-in-chief who thinks people like Edward Snowden are doing a good public service."
