First of all, some on this thread are under the impression that the shooter is a woman; it was a man. Anyway, the guy had left his car running in front of his house (stupid, and illegal in Washington). And as far as the furtive movement, the thief was shot in the back of the head as he was driving away - in fact, he actually made it several blocks before running into a utility pole. It seems unlikely that a person running out of their house would be able to see any kind of movement through the tinted back window and past several headrests.
Police investigators recommended no charges but somehow you send the DA know better. I was just wondering how.
