lost. now let's look at how the defense won. two major areas to focus on. first, tone is king. that's what my mom told me throughout growing up. throughout the trial and especially during closing, we heard a dramatic difference between defense attorney mark o'mara and prosecutor bernie de la rionda. we're not the only ones who noticed it. even o'mara pointed it out in his closing. >> does it really help you decide this case when somebody who is not george zimmerman's voice screams at you or yells at you and curses at you? no, i would contend. >> interesting point. john guy's close a little different. second, there were also the props. so we know the value of a good show. the defense had life-size cut-outs of zimmerman and martin and a concrete block they called a weapon because they say martin slammed zimmerman's head against it. the prosecution had a powerpoint slide show circa 1990. no bells, no whistles.
