you probably got it all wrong. >> you tend to take something disagreeable. you like skiing? i like skiing. you like pizza, i like pizza. you have two eyes, i have two eyes, we should totally go out. >> and good evening, thanks for being with us, i'm joie chen. headed into what might otherwise be a relaxed holiday weekend in florida there is instead tension over a closely watched court case with strong echoes of the controversial trayvon martin decision and some concern the verdict in this case might produce a similar an wished angd response. michael dunn, over an argument, he had no chance but to stand your ground. >> as a nation waited for a verdict in the so-called loud music trial the jury hit a wall in the deliberations and were sent back to their hotel for the evening. mike dunn was indicted in 2012 for murder after fatally shooting 17-year-old jordan davis during a dispute over loud music. dunn and his girlfriend stopped at a gas station where davis and his friends were parked in an suv. the jury heard from the fiancee. >> i hate that music. i heard pop pop pop. >> you got back in the passenger side of the car. did you see a firearm at that point in time? >> yes, michael was putting it into the glove box. >> throughout deliberations, jurors asked to watch that surveillance video twice. during closing argument, assistant state attorney john guy told jurors the case wasn't about self defense. it is rather the case of dunn's self-denial. >> jordajordan davis didn't hava weapon, he had a big mouth and the defendant wouldn't stand for it. >> the defense said dunn feared for his life. >> meeting with the dunn family we knew this was a clear case of self defense. >> but the case didn't add up. >> even people who have the right to self defense do not have the right to take the life of a child. >> he said he fires his nine millimeter handgun at the parked suv because he thought davis had a shotgun. >> there is my glove box, i'm looking out the window. and i said, you're not going to kill me you son of a (bleep) and i shot. >> no weapon was found in davis's vehicle. the case is drawing national attention to the parallels to trayvon martin. martin, a black 17-year-old was shot and killed by george zimmerman, during a dispute in sanford, florida. zimmerman was acquitted. while jurors deliberatewhether or not dunn committed murder when he shot and killed davis, protestors outside the courthouse had already made their decision. dunn could face life in prison. sarah, going into the weekend what happened? >> jurors asked the judge, listen we've hit a wall, could we break for the evening? he said yes. >> what does that mean, hit a wall? is there a specific count they're having trouble with? >> i think a few. earlier in the afternoon they came back, on some of these verdicts, if we agree on this, if we agree on this, what should we do in this case? the judge gave them some guidance. they are going head to head on whatever's happening behind closed doors. there seems to be some type of confusion perhaps or it will soe of battle because clearly they haven't come out with a verdict. >> they have asked for material, wanted to review things? >> clearl pretty standard, dotting all of your i's and dotting your t's surveillance video, so on so forth. it's not that uncommon. in this case they're right on par with what would be happening. >> so we would not hear from them again? >> probably through the weekend. >> going into a holiday on monday, wee will see, "america tonight"'s sarah hoye. from fort lauderdale, florida, ken, we appreciate your insight on this. we hope you can help us read the tea leaves what's going on here. you wouldn't think jurors would want to wait out through the holiday weekend. >> that might be enough to get you to all agree to a verdict and go home. but if you're not close and apparently this jury was not, they're going into the weekend to deliberate. and they're doing the job that we expect them to do. they're deliberating and there's probably a lot of arguing and looking at evidence, and sifting through the testimony that these jurors are doing and they're coming to head on certain issues that they have to resolve in order to have a unanimous verdict. all 12 jurors have to come to agreement on each count. >> as sarah pointed out they asked quite a few questions. some of the information they received has to do with how to process whether this is a first degree murder case, second degree manslaughter, this was laid out for them as was the sentencing guidelines on all that. >> well, sentencing is something separate and apart. the judge is totally in charge of sentencing and so the jury has no information concerning sentences or possible sentences. the jury's sole determination is to decide whether the evidence proves to them beyond and to the seclusion of every reasonable doubt the elements of the crime charged or a lesser-included crime. so for the first count, first degree murder the jury has to decide, is hefully of that? they decide there, that hasn't been proved yoord the beyond a e doubt and on to manslaughter. >> there were counts before the jury. >> exactly, one count of first degree murder, three counts of attempted first degree murder and there's a count of shooting into a -- shooting a missile into a vehicle which is shooting the firearm into the car. so we can speculate that if the jury is hung up on one count, it could be the first count of first degree murder. but again we would be speculating as to that. we really don't know what's going on in that jury room. >> and when you say shooting a missile into a vehicle, this is going to sound fairly confusing to people. but is that just the wording of florida law? >> well, florida law, when you read all the florida law to the jury, and some of it has to be read over and over again because there's multiple counts, it can be confusing. that is always a concern for a prosecutor because confusion is lead to reasonable doubt. so the prosecutor's job in closing argument is to really put all the evidence together, and show the jury how the law applies to the facts in this case, and warrants a conviction. of course the defense attorney's job is to show the jury there is reasonable doubt, this is confusion, there is lack of evidence or conflict in the evidence and that is probably some of the debate that's going on right now with this jury back in that jury room. >> and you and i talked about this earlier in the week, that the prosecutor did present to the jury that hey, the first degree murder count that could be second, why did she do that and what was sort of the reasoning presented there? >> well, in the evidence that i've seen presented in this trial it is my opinion, having been doing this for 27 years and i was a homicide prosecutor here in florida this is a very strong second degree murder case. there is an argument that it is first degree murder but it is not as strong in my opinion as a second degree murder conviction. the premeditation here is really a matter of seconds. and it's not very long. it is nothing in florida law that dictates how much time is required for premeditation but the jury could potentially look at the evidence in this case and decide there is not enough time for premeditation. this is a classic case of second degree murder. the music's too loud, they're disrespecting him, he grabs his gun and starts to fire. a classic case of second degree murder. maybe we can speculate the debate is whether or not it is first degree or second degree murder. debating whether it's an outright acquittal or a not guilty verdict. >> we won't know until next week. thanks very much criminal defense attorney ken padowitz in florida. thank you. >> when we return. another round, coming around. no rest for the weary in winter. what's left? and later in the program, a digital valentine. if you are looking for love online, it may be wise to consider rebranding. >> what's the person thinking? you quit your job to protest human rights violations and move to tibet. how does that benefit me as a boyfriend?
