@widewing. Point blank range, only three hits, two from behind, none center of mass. Maybe this meets your standard, but I'd rather not have this level of marksman escalating holdups to shootouts. He stopped the robbery. Great. He didn't make anyone safer, which is my point.
Anyway, as I keep saying, I'm not here to take a position on US gun control. For the record, I don't think it would make much difference either way. You guys don't really have a gun problem, you have a violence problem, as evidenced by the fact that non-gun murders are also off-scale compared to every Western nation. There's no easy ansmmwer to this, but the good news is that violence generally is in long-term decline. As American society continues to evolve, gun rights and gun crime will both become non-issues, just as they are in frequently cited Switzerland. Or even Canada.
I completely agree with your second point. We really have a serious violence issue here in the US. The culture is broken... It's not gun related, although guns get used frequently. Take away legal guns and the violence would not subside whatsoever. Until we as a nation are willing to accept that and do what is required to change the culture, it won't get better. Think about this... The shooting rate in Dodge City at it's height was a tiny fraction of what it is in Chicago today. Everyone was armed. Most of Dodge City's shootings involved very young cow hands getting drunk and arguing. There was no systematic crime. There was no culture of violence like we see today.
I would argue that the presence of an armed felon waving a gun around is grounds for immediate action. Why? Perhaps they would not shoot or beat anyone if everyone cooperated. However, it's a mistake to assume that a brazen robber would not use his gun without provocation. It's a more frequent occurrence now that ever before. You must assume that if they have a gun, they will use it. Inasmuch as the gun-toting robber never even saw the man approach him... Even unarmed, one could have whacked him with a chair, and disarmed him. However, the old man had a gun, was not young enough to risk a fight. I figure the old guy was more angry than frightened.
To know where I'm coming from, I should provide an overview of my experience. I have a long background with firearms or all type...
1) I am well versed in the law. All gun owners should read and know the laws governing gun ownership and you rights to use a gun in self defense for where they live. There's no excuse for not knowing.
2) I'm just weeks short of 60 years old. However, I've been very well trained. Both in the military and later working with various Federal agencies and the DOD. I design shot counter sensors for various weapons, such as the M4/ M4A1 SOPMOD/M16, M9, Beretta 96, Sig 550 series rifles, Sig pistols (P226, P228), Mk.46, Mk.48, SCAR light, SCAR heavy, H&K 416, MP5/10, MP5 and so on. We tested on the Mk.19 and Mk.47 grenade launchers as well, although we only used inert training ammo (too bad, making big bangs is much more entertaining). I get to extensively test them on the weapons and have worked with SOCOM quite a bit. I've had opportunities to verify function in tactical exercises. I'm one of a very few civilians who has had a chance to play with the old Stoner 63. The SEAL armory at NSWC Crane still had some of these in the late 90s and probably still do. The Stoner 63 was the rifle to DOD should have procured instead of the M16, because it is simply a much better, more reliable weapon.
3) More than 45 years of firearms experience, and have competed with handgun (revolver and pistol), shotgun and rifle. I still do cowboy action shooting events when I can, but it's getting tougher to find the time recently. It usually involves two days of travel as I refuse to transport weapons via the airlines. I get to the range, indoors and outdoors, 4 to 6 times a month for several hours at a time. My last visit was this past Saturday, and I brought my new Savage 11/111 (.300 Win Mag) to zero a newly purchased Leatherwood 7-30x50mm Mil Dot scope at 200 yards (longest range near to where I live). Once that was done, I spent an hour plinking with a .22 cal Henry lever rifle... Much fun, that little Henry, and you can shoot for days for the price of 20 rounds of Hornady A-Max Match Ammo for the Savage (at $2 a round, you bore sight before going to the range).
