This is enormous. I think it goes a long way to take the wind out of the "Justice for Trayvon" stuff.
It also says to the all-female jury: Here is an African-American woman who has the courage to stand up for the truth.
Her courage in standing up for the truth not only provides an example for them. It also provides a significant amount of "cover" as well for them to rule according to the truth and the law, and not according to political correctness and the rule of the mob.
Glad someone else got the importance of that.
