The president defines the question: If Trayvon Martin was of age and armed, could he have stood his ground?

The president addressed the pain being felt by African American communities across this country as well as any that really care about justice in the wake of Trayvon Martin's killer going free. Here's the president speaking (transcript here):



Yes, the president spoke powerful words when he said "Travon Martin could have been me 35 years ago." Beyond the president's heartfelt expression of that pain, though, he proved once again why he is the president this country needs (though I am not always sure deserves). This is the line in his speech that really called Americans to task on what can be done going forward.
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.
The president just told us in his own eloquent words what the most important part of the legacy of this tragedy will be. Will we come together and push back on laws that make redefine self-defense to mean 'shoot first, ask questions later?'
