Assistant D.A. John Guy presented the prosecution's rebuttal on Friday afternoon following the defense team's closing arguments in the murder trial of George Zimmerman. In his remarks, Guy asked the jury to use their "God-given common sense" in their deliberations on Zimmerman's guilt. 

"If that defendant had done only what he was supposed to do - see and call - none of us would be here," said Guy, later adding, "And let me suggest to you, in the end this case is not about standing your ground, it's about staying in your car, like he was taught to do; like he was supposed to do. And he can't now cloak himself with the noble cause of a neighborhood watch coordinator, violate its cornerstone principle and expect you to absolve him of his guilt. 

Guy also called on jurors to reject the defense's claim of self defense, saying that it was a "physical impossibility" for Trayvon Martin to have seized Zimmerman's gun.

"He couldn't have gotten the gun, he couldn't have! ...They wanted a reason? It's a physical impossibility!" he said. "The defendant didn’t shoot Trayvon Martin because he had to; he shot him because he wanted to. That's the bottom line."

On more than one occasion, the attorney invoked the quote "to the living we owe respect, but to the dead, we owe the truth," adding a question to the jury the final time: "what do we owe Trayvon Martin?"

"The last thing he did on this earth," Guy said, "is try to get home."

The jurors are set to return to the courtroom for jury instructions at 2p ET, following a lunch break.
