Interesting. This article seems to help the prosecution more than the defense. According to the article:
"In the New York City police department, for example, officers involved in gunfights typically hit their intended targets only 18% of the time, according to a Rand study. When they fired 16 times at an armed man outside the Empire State Building last summer, they hit nine bystanders and left 10 bullet holes in the suspect—a better-than-average hit ratio. In most cases, officers involved in shootings experience a kaleidoscope of sensory distortions including tunnel vision and a loss of hearing."
Yet, according to Jodi, she was able to accurately shoot a moving target in the head at the height of her fear.
Additionally:
"Glennon was a police-academy trainer, unusually well schooled in survival skills. But from the moment he saw the revolver, his mind entered a state unlike anything he’d experienced before. “Oh s—! Gun!” he said, spinning his body hard to the left, missing a bullet by inches or less.
Without his conscious knowledge, the sight of the gun had sent a signal to his brain stem, passing a message to his amygdala—the primal, almond-shaped mass of nuclei that controls the fear response from deep within the brain’s temporal lobe. The amygdala, in turn, triggered a slew of changes throughout Glennon’s body. His blood vessels constricted so that he would bleed less if he got wounded. His heart rate shot up. A surge of hormones charged through his system, injecting power to his major muscle groups should he need to fight or flee."
In this case, Travis' reaction to seeing the gun (if he indeed saw it) contradicts what should have happened according to this paragraph. Instead of fear and flight, he lunged (according to Jodi).
