0 then? >> trayvon benjamin martin. >> my brother. >> trayvon? >> yes, there's absolutely no doubt in my mind that that is george zimmerman. >> after consulting with council not to testify, your honor. >> if this person, this man again were carrying a firearm on their waist, where would the gun be right now in relation to me? >> it would be at your left inner think. >> would the injuries on the back of his head be consistent with this. >> why would he get out of the car if he thinks that trayvon martin would be a threat to him? why? because he's got a gun. he's got an equalizer. he wants to be a cop. >> the person who decided this was going to continue, that it was going to become a violent event was the guy who didn't go home when he had a chance to. >> i almost wish that the verdict had guilty, not guilty, and completely innocent. because i would ask you to check that one. you got to check the not guilty. check the innocent one too. trayvon martin may not have the defendant's blood on his hands, but george zimmerman will forever have trayvon martin's blood on his. >> the verdict, we the jury find george zimmerman not guilty. >> how can they say not guilty for anything? this man did not follow the law! >> the justice department shares your concerns. i share your concerns. and as we first acknowledged last spring, we have opened an investigation into this matter. >> i think the prosecution of george zimmerman was disgraceful. as happy as i am for george zimmerman, i'm thrilled that this jury kept this tragedy from becoming a travesty. >> he needs to be held accountable for hiss crime. that is not what happened today. >> as the justice department said yesterday, they first acknowledged last year that they had an open investigation into trayvon martin's death and they continue to evaluate that evidence. >> george zimmerman was never guilty of anything except protecting himself with self-defense. >> you have a 17-year-old kid who was minding his own business, wearing a hoodie, gets accosted, gets followed by an individual who wants to be a cop. >> cases are brought on the merits and the merits are evaluated by the professionals at the department of justice. and the president expects, as in every case, that the process will be handled in the way it should be at the department of justice and certainly not here. >> we are very, very saddened, but we accept the jury's verdict in this case. >> the evidence didn't support prosecution, the justice department engaged in this, the president engaged in this and turned it into a political issue that should have been handled exclusively with law and order. >> we go to sanford to see how this case started. we go back to the scene to trace scription of zimmerman and martin. >> if you take a look at this 7-eleven, you'll see that it's like any other 7-eleven. at approximately 6:24 made the apartment casting some light out and when the lights aren't on here, i can tell you that i can't identify someone five feet in front of me, it's that dark back here, at least now. and i assume the lighting conditions back here are very much similar to what they were at night on february 26th. this is the area right here, to my right, which is where the decedent's body was found and where george zimmerman says that he was lying and where he hit his head was pounded against the cement was about here. and of course, here to orient you, this is the area right here. and according to george, george had walked -- george was down to my left. he had made his phone call to the police. and he intended to go this direction and go towards the clubhouse which was down there. and between the last second that george zimmerman, phone records show, between the last time he hung up with the police, and the time a 911 call was put by a citizen that there was something going on, about a minute and 24 seconds, so presumably, something happened right about here and it will be the jury's job to decide who was the aggressor, whether george was defending himself or not. and of course that's a task we give the jury and the prosecution has to prove beyond a reasonable doubt its case and the defense has to prove absolutely nothing. now the jury has spoken, but as in many trials, questions still linger as to what really happened on that dark night, especially during those four crucial minutes. defense attorney ted williams joins us, welcome, ted. you and i went out to the scene, you were there with me when we walked back there. and there was a four-minute period, and the four-minute period was the time that george zimmerman told him he was going to run and i'm going to subtract a minute off to three minutes because someone has to go from the fight to making the phone call to 911. is that time reference important and why? >> yeah, it's important and i can tell you, greta, i've been racking my mind about it because those are the four minutes where trayvon martin, if he so wished could have ran and perhaps gone home. and i tried to put myself in the place of trayvon for those four minutes. and all i can think of is that four minutes to us, and if you remember, mr. o'mara, the defense attorney played it in court and emphasized these four minutes. i have thought about it. trayvon, i wonder what is going through his head, because it's dark, it's rainy, a silhouette is following you, you're on the phone with genteel, do i want to bring this person home with me? why is this person following me? and all of that was going on in this young child's mind i would have to believe. and that's a lifetime for him. and greta, you know how dark it was back there. sure whether he was really scared or whether she was standing to confront or whatever. but absent proof beyond a reasonable doubt, that high burden, that's what the prosecution was dealing with that made it so difficult. it's the burden of proof in the case. >> it was the burden of proof, and you're right, i think unfortunately, when you look at the evidence when you look at this four-minute period, that there's clearly, in the minds of the jurors could have been reasonable doubt. so i could. agree with you more. greta, until this moment, there's another question mark. why do they go with second-degree murder in this case? when you look at the totality of the circumstances, it's incredible. >> ted, thank you. and straight ahead, what was george zimmerman thinking when he heard the jury deliver its verdict. his brother robert zimmerman is next. also you're going to hear from alternate juror number 54, he was there the entire time for testimony and what did he find most compelling?
