If you shoot someone in the chest or head with a firearm, you are doing the exact same thing as a hunter killing a deer.
1.) The deer is not attacking you. (Attack means unprovoked violence upon another, in the context of self-defense.) 2.)You are not going to eat your human attacker. (I hope.) 3.)If you shoot a deer and fail to kill and collect it, most States can charge you with "wanton waste" or some such. If you gut shoot a human attacker and he ceases the attack, you either disarm him and render aid or hold him if he still has the gun, and watch him bleed out, I guess. I never want to be in that situation myself, and practice other things as much as possible to avoid it. 4.) If you are equating the emotional context of shooting a deer vs. shooting a human, it goes against human nature to want to kill another human, and for many, a deer, too. Read
On Combat, by LTC Dave Grossman; it explains this tendency to avoid killing another human very well.
Why do rifles exist if you only have to worry about shooting 3-5 yards?
Do you carry a rifle as you go about your day? Handguns are a compromise. Some can shoot them farther more accurately than others, but speed and accuracy are a continuum that changes with range.
Does rescuing a hostage somehow make you shoot more accurately?
No. This is why cops are trained to keep the situation static until the professionals that train for such occasions show up. (SWAT, CIRT, whatever you want to call them.)
I actually DO have some training in door kicking, and I still would not want to attempt it.
So if you're not trying to rescue a hostage, your plan is to just spray and pray?
No; we all (hopefully) train to be as accurate as possible as fast as possible. As the range decreases, speed becomes more important, precision less so. Cops train to distract the hostage taker while the SWAT team sets up to do what they do.
While in ROTC, I participated in a 'hostage situation' scenario. As freshmen, we were the hostage takers, the sophomores were the hostages, and juniors and seniors were the anti-terrorist unit. (we were supposed to be terrorists; a domestic hostage situation is handled differently.)
As one of the 'terrorists' assigned to watch the hostages, both the hostages and the other 'terrorists' were horrified that when the attack on us was initiated, and entry was made in the building, I turned and 'executed' (by firing blanks at the wall over their heads) all of the hostages. The officer in charge of the scenario later asked me why I did that. I answered "Because that is what they are trained to do. They do not expect to survive-they view themselves as martyrs"
I had a little (very little) training in door kicking, and it is a skill that requires precision and speed. very few can do it, and while I did it OK then, it's a perishable skill, one I'd not want to attempt now.
No, but it's a far more realistic possibility with an edged weapon with a pistol.
This tells me you have had no realistic training with guns
or edged weapons.
I just speak normal English, sorry.
It's not your speaking (writing in this case) of English, it's the comprehension.
