So, here's a look at some more details. The killer claims Trayvon sat up after being shot and said something like "You got it" then fell over. George, the shimmy 'expert', then shimmied out from under Trayvon, stood up, holstered his gun, and then jumped on Trayvon's back to 'restrain' him. It's Zimmerman's story that Trayvon was still moving, trying to sit up, and speaking after he'd jumped on him to pin him down. To quote:
“It felt like he was hitting me with bricks, so, I remember, once I shot him, I holstered my firearm and I got on top of him and I held his hands up because he was still talking,” he said. “And I said, ‘Stay down. Don’t move.’ ”
Is this account even remotely possible? Short Answer: No.
Here's the longer answer:
Medically, we know Trayvon would have become unconscious within 4 to 10 seconds. We know this for several reasons. First, there is no doubt, given about a third of his heart was instantly obliterated by the gunshot (as documented at autopsy) that he had no BP and no pulse from the time the bullet struck his heart. The heart stopped beating, and the blood that would have been pumped out to vital organs, like the brain, instead drained out of the gaping hole into his lungs and thoracic cavity. So, we have a pulseless, BP-less person as a matter of FACT, not speculation, from the time of the gunshot onward. Start the clock ticking at this point...
Second, we know what happens with scientific certainty when the brain is deprived of a blood supply and therefore oxygen. It's been tested on subjects who underwent experiments in which their brains were suddenly cut off from blood/oxygen via a cuff around their necks. These experiments were conducted back in the 1940s during WWII by Dr. Ralph Rossen at a state prison and later replicated elsewhere. The device used was called a KRA cuff. All the subjects (and there were several hundred of them totally) lost consciousness within 4 to 10 seconds max, with the time to loss of consciousness being 5-7 seconds in the majority of subjects. Trayvon's loss of consciousness would likely have been closer to the first number (4 seconds) than the longest (10 seconds), since he'd been running, was in a state of panic, had just been in a fight for his life, and his organs would have been using oxygen at a higher rate than a person sitting quietly in a chair or lying on a bed in the moments just prior to the sudden blood/oxygen deprivation.
Now, if you look at George's story as he tells it, it would take him a second or two to realize he'd actually shot Martin (he himself claims he wasn't sure), and it (allegedly) took a few seconds for Martin to sit up and say "You got it" or whatever initial utterance George wants to place in his mouth, another second for him to fall over again, a few seconds for Zimmerman to shimmy out from under his body, another second or two for Zman to stagger up to his feet after that "horrific" (alleged) beating he'd just received, a second to holster his gun, and another second or two to climb on top of Martin and pin him. You're looking at 8-10 seconds for him to physically complete the series of actions he describes BEFORE he'd be on top of Martin and telling him to not to move and (allegedly) listening to him continue to speak. But Martin's brain has been without blood and oxygen this entire time, and his blood has been pouring into his thoracic cavity unchecked...
See the problem? There's no way Martin was even conscious at the point Zimmerman alleges he was talking and trying to get up. Furthermore, even had he been, when Zimmerman put his weight on Martin's back, any air remaining in Martin's lungs would have been expelled by the applied external pressure, and there would have been no refilling the lungs to allow for speech.
As you say, the Devil is in the details...and these details don't lie.

In other news, CTH discussed this question in August 2012.
Here's what an actual medical expert says:
Quote:
George Zimmerman may have shot Trayvon Martin in the heart, but that didn’t kill him instantly. The 17-year-old survived for several minutes, according to two experts who reviewed Trayvon’s autopsy for the Orlando Sentinel. “You’re talking about minutes, at least, for him to survive,” said Dr. William Anderson, a forensic specialist and former deputy medical examiner for Orange and Osceola counties. “I think he would have been conscious … for a little time, anyway.”
What killed the Miami Gardens teenager was massive internal bleeding, said Anderson and Dr. William L. Manion, a board-certified anatomical, clinical and forensic pathologist and lawyer in Mount Holly, N.J.
At 7:17 p.m. on Feb. 26, the bullet that killed Trayvon entered his chest square-on, just to the left of his breastbone, according to his autopsy. It punched a hole in his right ventricle, the lower right chamber of the heart, and broke into three pieces. The bullet’s lead core — the bulkiest part — was found just behind his heart, still inside the pericardium, the sac that contains that organ. Two other fragments were found next to his right lung, which had been perforated and collapsed, the report said. When Sanford firefighters arrived 10 minutes later, at 7:27 p.m., firefighter Stacey Livingston checked him over.
During an interview March 24 with agents with the Florida Department of Law Enforcement, Livingston said: “He had a small bullet hole in his chest area that wasn’t even bleeding,” Not on the outside. Inside, however, his chest cavity had filled with 2,300 milliliters of blood, according to the autopsy. That’s about one-third of a healthy person’s total blood volume, Anderson said.
Trayvon’s heart had kept pumping, both pathologists said, but with each contraction, blood was leaking or gushing into his chest, depending on the size of the bullet hole. The two doctors agreed that Trayvon remained conscious for a time. Anderson suggested the teenager may have been conscious for several minutes. Manion estimated it at just 20 to 30 seconds. “He certainly would have experienced pain,” Manion said. The Miami Gardens teenager would have remained alive for a few minutes, both doctors agreed, as his wounded heart continued to pump.
One piece of evidence that Trayvon did not die instantly, both doctors said, was the color of his fingernails. Shiping Bao, the associate medical examiner in Volusia County who performed the autopsy, wrote that Trayvon had “cyanotic nail beds.” That means they had turned blue, something that happens when there’s not enough oxygen in the blood. Because Trayvon’s heart was weakened by blood loss and dropping blood pressure, it could no longer pump blood to his lungs. That means vital organs, including the heart, were no longer receiving the oxygen-rich blood they needed.
His heart eventually went into defibrillation, Manion said. That means the muscle fibers within it continued to contract but no longer in the regular rhythm needed to sustain life. A few minutes after that, the last signs that a heart could be revived — electrical signals — would have ceased as well, Anderson said.
Keep making things up; we'll just keep debunking them.
