Jury selection are many methods used to choose the people who will serve on a trial jury. The jury pool is first selected from among the community using a reasonably random method. Jury lists are compiled from voter registrations and driver license/state ID renewals. From those lists, summonses are mailed. A panel of jurors is then assigned to a courtroom. The prospective jurors are randomly selected to sit in the jury box, then are questioned in court by the judge and/or attorneys. Depending on the jurisdiction, attorneys may have an opportunity to mount a challenge for cause argument or use one of a limited number of peremptory challenges. In some jurisdictions that have capital punishment, the jury must be death-qualified to remove those who are opposed to the death penalty. Attorneys sometimes use expert assistance in systematically choosing the jury, although other uses of jury research are becoming more common. The jury selected is said to have been "impaneled." In three studies legal authoritarianism, attitudes toward psychiatrists, and attitudes toward the insanity defense were examined as predictors of conviction-proneness in insanity defense cases. Some experts believe that 85% of cases litigated are won or lost in the jury selection phase.

Caylee Marie Anthony (August 9, 2005 – 2008) was an American two-year-old girl who was reported missing in Orlando, Florida, in July 2008, whose skeletal remains were found in a wooded area near her home in December 2008. Her then 22-year-old mother, Casey Marie Anthony, was tried for the first degree murder of Caylee but was acquitted. She was, however, convicted of misdemeanor counts of providing false information to police officers.

Caylee lived with her mother, Casey, and her maternal grandparents, George and Cindy Anthony. On July 15, 2008, Caylee was reported missing to 9-1-1 by Cindy, who said she had not seen Caylee for 31 days and that Casey's car smelled like a dead body had been inside of it. She said Casey had given varied explanations as to Caylee's whereabouts and finally admitted that day that she had not seen her daughter for weeks. Casey fabricated various stories, including telling detectives the child had been kidnapped by a fictitious nanny on June 9, and that she had been trying to find her, too frightened to alert the authorities. With the child still missing, Casey was charged with first degree murder in October and pled not guilty. On December 11, Caylee's skeletal remains were found with a blanket inside a trash bag in a wooded area near the family home. Investigative reports and trial testimony alternated between duct tape being found near the front of the skull and on the mouth of the skull. The medical examiner mentioned duct tape as one reason she ruled the death a homicide, but officially listed it as "death by undetermined means".

The fatal shooting of Trayvon Martin by George Zimmerman took place on February 26, 2012, in Sanford, Florida, United States. Trayvon Martin was a 17-year-old African American male who was unarmed. George Zimmerman was a 28-year-old multi-racial Hispanic American, who was the community watch coordinator for the gated community where the shooting took place.

While on a private errand, Zimmerman saw Martin walking inside the gated community where Martin and his father were visiting his father's fiancée. Zimmerman called the Sanford Police Department to report Martin's behavior as suspicious. Shortly afterwards, there was an altercation, which ended with Zimmerman fatally shooting Martin once in the chest at close range.

When police arrived on the scene Zimmerman told them that Martin had attacked him and that he had shot Martin in self-defense. Zimmerman was bleeding from the nose and two vertical lacerations on the back of his head.EMTs treated Zimmerman at the scene, after which he was taken to the Sanford Police Department. Zimmerman was detained and questioned for approximately five hours. A statement was videotaped, and he was then released without being charged. Police said that they had not found evidence to contradict his assertion of self-defense.
