Among the victims in Las Vegas were 36 women and 22 men; 51 were killed by a single shot, while seven were hit by multiple rounds; 34 suffered fatal gunshot wounds to the body, while 21 were struck in the head or neck and three were struck in their extremities. In addition, 851 people were injured in the attack, including 422 who suffered non-fatal wounds from gunfire.
With bullets exiting the shooter's weapons at a velocity of about 3,000 feet per second ― about three times as fast as a bullet fired out of a handgun ― and spinning at thousands of revolutions per second, the consequences for anyone hit directly were dire.
"You've got a relatively small cross-sectional area with a tremendous amount of kinetic energy lined up behind it, so that just penetrates," said Arthur Alphin, a ballistics expert and former West Point professor who has testified in a number of multiple shooting cases.
The autopsies describe bullets carving through flesh, leaving massive trauma in their wake. One victim suffered a gunshot wound to the left upper back. The round appeared to be tumbling end over end at the moment of impact, said Alphin, likely a sign that the gunman's weapon had begun to overheat from firing so rapidly, sending the bullet on an unstable trajectory out of an expanded barrel.
After being struck in the back, the round coursed through the woman's body, ricocheting off a rib and perforating her left lung before stopping between her eight and ninth vertebrae, where a medical examiner recovered the bullet.
The autopsy for the woman described at the beginning of this article shows she was shot in the forearm. The bullet passed through her arm twice and then entered her body.
"I'm thinking that this person had their arm up at the shoulder, but bent back at the elbow, as if scratching their ear or trying to shield their eyes or keep a hat from flying off their head," said Alphin.
It's also possible she was trying to shield herself.
Another report describes a woman who was struck in the head. As with the other victims who suffered direct shots to the head, the impact caused "instant death," Alphin said.
"The only good thing is she didn't suffer. She felt no pain at all," he said. "Some of those others, even though they died with the chest cavity wounds, they survived on the ground for 60 to 90 seconds, their heart continued to beat, the blood filled up into the pleural cavity and the thoracic cavity, their brain was still functioning, and they knew they were dying and they were in pain. At least this poor woman, it was instant."
Where did I argue that the 5.56 was "more destructive" than any other ordinance? I didn't, I posted an article documenting it's particular lethality and the doctors quoted compared them to a 9mm handgun's bullets. THEY made the comparison without qualification or claim that the AR-15 was somehow the worst.
If you would have noticed, the argument was based on the VELOCITY of the round fired by the AR-15, not it's particular caliber. But in order to do that, you would have had to read the article as written. The comparisons are what they are, not what you're trying to misrepresent them as. And they are as factual as the non-related dreck you just posted.
