There are 22 million veterans, 1 million law enforcement personnel, and 300 million guns in America.
LOTS of people can handle guns in America.

I don't believe 22 million veterans, however well trained with rifles and small arms, have ever had to actually kill someone and even less so in close combat. Also, I trust the 1 million properly trained (and I think it is higher than that) law enforcement officers to properly use a handgun.
I do not trust the vast majority of untrained Americans to properly handle a handgun in a moment of extreme physiological terror. With a rifle, from a longer distance, the entire situation is different. With a handgun, the action is on top of each other. You are in close proximity. The amount of adrenaline that is injected into your body training to manage and channel. Firing, precisely, amid a torrent of emotion, psychological energy, physical responses, and nervous system overload is extraordinarily difficult without the proper training.
This is called scotopic vision in technical literature and it takes significant training to harness and use effectively. Someone who is under duress of an attack has to master their physiological response in addition to maintaining focus, narrowing peripheral vision, utilizing proper hand-eye-coordination, ensuring the depth perception stays the same, not fixating on one point and neglecting the field of vision, and channeling their adrenaline to maximize their sensory perception without sudden temporary blindness and/or loss of motor control. And all in a split second.
I do not trust the average American to accomplish this successfully with a handgun.
Police officers, psychologists, security experts, and medical professionals all warn against the dangers of untrained civilians believing they can fire for effect in crucial moments of close range. With the proper training someone can indeed overcome the physiological responses and be effective, but the vast majority of Americans do not have that training.
Lots of people can carry handguns in the United States. Few people can properly handle them in crucial moments of need. This isn't the movies. This isn't tv. There are extraordinary psychological, emotional, and physical challenges to ending someone's life...even for law enforcement.
