And for those who resist that idea that we should think about something like these "stand your ground" laws, I'd just ask people to consider, if Trayvon Martin was of age and armed, could he have stood his ground on that sidewalk? And do we actually think that he would have been justified in shooting Mr. Zimmerman who had followed him in a car because he felt threatened? And if the answer to that question is at least ambiguous, then it seems to me that we might want to examine those kinds of laws.
