Four minutes later, O'Mara stood up and indicated the purpose of his demonstrative inaction.
"That's how long Trayvon Martin had to run," said O'Mara pointing out the length of time from when Zimmerman told the police dispatcher that he saw the teenager running to the moment he and Zimmerman began the lethal confrontation. "The person who decided this was going to be a violent event was the person who planned his move."
He brought out cardboard cutouts of two figures to show the relative sizes of Zimmerman and Martin. The figure representing Martin was a couple inches taller than the Zimmerman cutout.
O'Mara also lugged before the jurors a slab of concrete.
"That is sidewalk and cement. That is not an unarmed teenager with Skittles trying to get home... That is a teen using all means to inflict great bodily harm," he said.
O'Mara told the jurors that the fact that Zimmerman talked freely with law enforcement despite having shot someone and after suffering injuries was an indication of his innocence.
"We have factual innocence," insisted O'Mara.
John Guy, who got the last word, scoffed at O'Mara's suggestion that Martin had four minutes to go home, but instead confronted Zimmerman.
"Four minutes is not the amount of time that Trayvon Martin had to walk home," said Guy. "Four minutes is the amount of time Trayvon Martin had left on this earth."
The prosecutor said Zimmerman told at least 10 lies, which he showed to jurors in a power-point presentation and he also said Zimmerman changed his story in several other instances.
"What is that when a grown man, frustrated, angry, with hate in his heart gets out of his car with a loaded gun, follows a child, a stranger with a gun and shoots him through his heart?" asked Guy. "What is that? Is that nothing?"
At another point he asked, "Did he really need to, did he have to shoot Trayvon Martin?"
The jurors have been sequestered for nearly three weeks and according to most indications are eager to go home. The jurors were handed instructions and will have to weigh Zimmerman's right to self defense against the state's burden to prove his guilt in the death of Martin.
To convict Zimmerman of second degree murder, the jury will have to find that he acted with "ill will, hatred, spite or an evil intent," according to the state statute. To convict him of manslaughter they must find that he acted through extreme negligence and that even if he didn't intend to kill Martin, he acted with "utter disregard" for his safety.
The jury can acquit Zimmerman if they find that he reasonably feared for his life or feared serious harm at the time he fired the shot.
