Why CBS kept mum for four days about the sexual assault of correspondent Lara Logan by a Tahrir Square mob we just don’t know. Did Logan, flown from Cairo to a US hospital hours after the attack, request secrecy as a brutalized victim?

Were news executives, or Logan herself, concerned that news of the assault would detract from the “democracy” drama? Such a blackout is hard to imagine if, for example, a star correspondent had been similarly violated by Tea Party-goers at a massive Glenn Beck rally.
