Like most spokespeople, she was speaking extemporaneously and probably flubbed the lines. As purely a public relations matter, she would have been on more solid ground if she had just stuck with the last sentence "Our position is race did not play a factor." Admitting any wrongdoing by Crowley is opening the door for a lawsuit. Given that the commissioner is backing Crowley, paving the way for litigation is a bad idea."I think both parties were wrong. Our position is race did not play a factor."
My personal take on that line is that she was trying to appear evenhanded and sympathetic to Gates, and flubbed it.
(Kinda like Gibbs pointing out that the union for the Cambridge PD backed McCain, but instead of putting the whole foot in the mouth she just put in two toes).
