[23] The prosecution alleged that recordings of telephone conversations Zimmerman had with his wife from jail showed that they had been speaking using a code about their finances, with repeated mentions of "Peter Pan" in apparent reference to a PayPal account.

[57] In August 2012, the State's 6th Supplemental Discovery included 76 pages containing the audio statement from witness 31, three photos taken by witness 13 at the scene showing the back of Zimmerman's head, a flashlight on the ground, the FDLE report with analyst's notes, emails from the Sanford Police Department, copies of Tracy Martin's 911 call reporting his son missing and Zimmerman's Seminole County Sheriff's Office Academy application.

In her ruling, Nelson said that Zimmerman's attorneys needed to know whether Martin's school records and social media postings revealed any evidence that he had had violent tendencies.

[61][62] Martin's parents said the defense's request for school records and social media was a "fishing expedition" aimed at attacking their son and an attempt to assassinate his character.

Judge Nelson ruled that Martin's school records, history of marijuana use, fights, and photos and text from the teen's phone should not be mentioned during the trial.

[84] Zimmerman's attorneys had requested a Frye hearing regarding the admissibility of the testimony of the audio analysts, to determine if the methods used by them were generally accepted by the scientific community.

The prosecution wanted to use voice experts that had been hired by lawyers and news organizations to analyze the 911 calls recorded during the confrontation to determine whether it was Martin or Zimmerman yelling for help.

[97] The prosecution said Zimmerman was a "wannabe cop" who had participated in martial arts training, that he was looking for "people who didn't belong," and that he profiled Martin as "someone about to commit a crime in his neighborhood.

[131][132] Anthony Gorgone, a crime lab analyst with the Florida Department of Law Enforcement, testified that he found no traces of Zimmerman's DNA in scrapings taken from Martin's fingernails.

On cross-examination by O'Mara, Bahadoor testified that she discussed her testimony with the police and did not recall if she had said the noise moved from south to north during her initial interview with Chris Serino or FDLE.

During cross-examination by Bernie de la Rionda, Osterman said he was unsure how many copies his book, Defending our Friend; the Most Hated Man in America, had sold and stated that all proceeds would go for Zimmerman.

Donnelly testified that he had found it "distressing" to listen to the 911 tape due to his combat experience in Vietnam and said "There is absolutely no doubt in my mind that is George Zimmerman and I wish to God I didn't have the ability to understand that.

Meza said he had been working on his computer last year when he heard Zimmerman's voice being broadcast on a news report that his wife was watching on television.

During cross examination, Bernie de la Rionda suggested to Serino that Tracy Martin may have been in denial about his son's death and that's why he uttered "no."

[182][183] Bill Lee, former Sanford police chief, testified that he recommended the tape of the 911 call be played for Martin's family individually, rather than in a group, to avoid any improper influences.

"[185][187] Dennis Root, a former police officer with training in firearms and self-defense and a use-of-force expert, testified the fight between Zimmerman and Martin went on for some 40 seconds and was marked by a high level of fear and anxiety.

[190] State Attorney Bernie de la Rionda opened his closing argument on Friday, July 12 by telling the jurors that "a teenager is dead through no fault of his own" because Zimmerman had made assumptions about Martin and acted on them.

[197][198][Note 4] On Saturday, July 13, 2013, the day after deliberations began, the jury returned a verdict of not guilty for both second-degree murder and the lesser included charge of manslaughter.

The literary agent released a statement from Juror B37 on Twitter which said the "isolation shielded me from the depth of pain that exists among the general public over every aspect of this case.

A few variations regarding the definition of racial profiling include the notion that suspects are identified and approached due to physical, behavioral, psychological, or unwarranted factors such as race.

"[217] Attorney and former Court TV anchor Jami Floyd told BET, "It is clear that George Zimmerman pursued Trayvon Martin and that he shot him.

He said the prosecution had a tough case from the start, and, "as a legal matter, I don't see how they [the jury] could have reached another verdict, considering how the law works with regard to self-defense".

[214] Additionally, others developed the idea that Trayvon Martin was exploited in order for others to gain power off of his suffering, furthering race as an artificial and divisive tool.

[216] Other protests in support of the Martin family occurred in Washington, D.C., Los Angeles, San Francisco, Chicago, Denver, Baltimore, Detroit and New York City, among others.

[237][238][216] In response to the acquittal of Zimmerman, protests through a multitude of forms emerged, including films and documentaries, social media posts, and non-violent and violent rallies.

[214] The term "Black Lives Matter" was mainly integrated into social literature through hashtags on Twitter in response to the acquittal of Zimmerman, and has now grown in its prevalence and significance politically.

[242] The effects of BLM has been paralleled by countries around the world, shifting police brutality into the public eye and requiring reflection regarding the multitude of fields it impacts including economics, morality, and equality.

[242] In terms of Trayvon Martin and George Zimmerman, it enabled an outlet in which protestors could demand justice and disseminate a social power and strength within communities, with its participants perpetrating a widespread call-to-action through these protests and conventions.

[243] In order to utilize the shooting and case as education, officers and leaders engage in interconnected strategies which incorporate psychological and political concepts to better their systems.

The death of Trayvon Martin and trial of George Zimmerman has encouraged reconsideration of certain policing implications and enforced structures in order to prevent a similar incident and thus political outcry.
