Um, yeah, something big just went down at Discovery Channel’s HQ. Apparently a gunman held several people hostage earlier today while we were all obsessing about silly Apple products. Long story short, the police shot the baddie and the hostages weren’t harmed. The guy had “concerns” about the Discovery Corportation. Our guess it has something to do with replacing David Attenborough with Oprah for voice-over duty. wtop.com has the story.
