Tora! Tora! Tora!
We heard today that a woman driving a black Infiniti rammed security barriers approaching the White House, fled, and was shot to death by Capitol police. She had a one year-old child in the car.
I wonder what the odds are that she made a wrong turn, then panicked and fled when a bunch of cops started running at her with drawn guns, hitting a security barrier and a cop as she tried to flee.
Absent a motive, we might never know.
UPDATE: Given her history of mental illness, and some new details, the scenario above looks unlikely.
