No evidence has surfaced yet that Snowden’s revelations made a difference in this case, or that the perpetrators of Friday’s attacks used encrypted communications to conceal their activities. Many private-sector computer specialists surveyed by POLITICO were skeptical about those arguments, which if true would mesh with more than a year of warnings from intelligence officials about the growing ability of terrorists and criminals to hide their tracks online.
