obviously you don't understand the definition of "required"
So, you would say that a situation where an innocent was beaten and raped in an alley didn't require a firearm? I'd say it did require one and yet people survive those incidents on a daily basis.
If you honesty believe that only situations that resulted in the death of an unarmed person actually count as "required" firearms situations then it is you who does not understand the word. I'm allowing for injuries in my question. If there was not at least an injury, what was the requirement for a reload? So, once again, do you know of a situation where a reload was required, resulting in the death or injury of the defender due to not having a reload? Even in the data provided on the 3 reloads (let's face it, 2 reloads, the lion shot with a .32 doesn't count) there is no evidence that the reloads were actually "required". If you fired until empty and the BG was nowhere to be seen, would you reload? Well, yeah. Is it a "required" reload? NOt unless you have to pull the trigger again. Fact is, if you fired until empty what is needed, 99.99% of the time, is a little trigger control, not a reload.
Back on topic, I'm actually comfortable telling people that they don't need to carry a firearm at all if they don't want to do so. Oh my God! What if they get killed!! I'm also comfortable explaining the reasons that they should consider carrying, if they want to hear it. Either way, it's their decision, not mine.
I've spent 32 years of my life without a firearm on my person and never needed one. I have one now because I want one. I seriously doubt I'll ever need one, much less a reload. So, if somebody says "Hey, I carry a XYZ handgun. Do you think I need a reload?" I'll say no, I don't think you do because..." If they choose to carry one anyway, great. If they choose not to carry one, that's great too. I'm pretty comfortable knowing that the odds are very high they'll never need the gun at all and if they do need it, they'll probably not need to fire a shot and if they do fire a shot, it will probably be 1 or 2 and if they fire more than 2, they will probably not need a reload. Also, if they do fire a single shot in SD it will be all over the news. See, things like that are EXTREME rarity (read, has never happened here except between small time drug dealers which doesn't count in my book) where I live. If they weren't, I wouldn't live here, but that's a topic from another thread.
As for your example above, I'm talking about reloads carried on your person. I have reloads available at home and work because there's no reason to not have them. I'm talking about taking reloads out on the street.
