We are all Trayvon Martin. He was a boy who did nothing wrong, and Zimmerman came after him filled with ideas and a bullet.
My take is that the Stand Your Ground laws were set into motion to amplify existing self-defense laws and give license, and potential harbor, to a particular group of citizens, as they carry their guns. Take a look at this article:

It's time to end NRA/ALEC sponsored Stand Your Ground laws! Call your Senators and Members of Congress; make your voice heard; make your vote count.
