Navy Leaned on Wired Over Non-Existent Weapon

Publication asked to un-publish a five-year-old story about a request for an airborne laser

In its mounting campaign against leakers, the U.S. government isn't just going after officials who revealed weighty secrets like the White House's drone strike "kill list" or its plan to sabotage Iran's nuclear sites. Federal agents are also chasing a leaker who gave Danger Room a document asking for a futuristic laser weapon that could set insurgents' clothes on fire from nine miles away.

It's an odd investigation, because the energy weapon doesn't exist; the unclassified document describing it reads almost like a spoof of the laser system out of Real Genius; and this is 2012 — nearly five years after the leak in question.
