"good evening, everyone. i'm angela corey, the special prosecutor for the trayvon martin case . just moments ago we spoke on the phone with sybrina fulton and tracey martin. we told them weeks ago that we would get answers for their questions no matter where the quest led us. and it is the search for justice for trayvon that has brought us to this moment. the team here with me has worked tirelessly looking for answers in trayvon martin's death."
"When we charge a person with a crime, we are equally committed to justice on their behalf as we are on our victim's behalf. so we're here to do that on behalf of our victim, trayvon martin, and on behalf of the person responsible for his death, george zimmerman." http://i2.cdn.turner.com/cnn/2012/images/04/11/angela.corey.speech.pdf
If it is determined that Zimmerman was acting in self defense that will certainly have been the case.
