facing a possible death sentence, jonathan graham pled guilty to first-degree murder and rape. >> i don'tdent, other than i pushed him against one of the walls. >> graham had no way of knowing that 20 years later, technology would eventually catch up with him. >> the forensic science behind this investigation is what sealed jonathan graham's guilt, even without ever stepping a foot in court. >> over my career, i've seen some amazing things. and that coupled with good detective work, there's just no end to what we can do. >> we here in science, in forensics, we're here for the truth. we're not here for the prosecution, we're not here for the defense. we're here for the truth. >> he will spend the rest of his life in a state penitentiary.

trayvon martin is dead, renisha mcbride, marley graham, jonathan farrell.t keeps going on and on and i'm tired. >> i want to pun pack that just a little bit, rinku, because is this a racist result? you had a justice system prosecute michael dunn for the shooting. a jury, using the law they had, convicted him on four counts, out of five. is this a racist result or is this the way the criminal justice system is supposed to play out? i mean, he was convicted of something. >> well, the big problem here is that we're still debating whether or not race is a factor in this case and in this trial. and for as long as we're debating if, we cannot get to the how. so, from my perspective, the problem with the way the prosecution has carried out both of these trials now is that by refusing to put race on the table, they enable the bias that stand your ground codifies to continue and to remain invisible, remain unclear and hidden. so, tania weathersby had a great piece where she said, what michael dunn respected from that interaction was not respect, but submission. stan
