This idea that you need a weapon to defend yourself is based on what reality? Sorry but I've been face to face with the Taliban and was perfectly capable of talking my way out of that altercation. A firearm gives a false sense of bravado and an entitlement to escalate. Does anyone have the statistics on the number of firearms that were turned upon their owner? I distinctly recall law enforcement telling me that unless you are well trained, like the military or law enforcement, a weapon is not that great of a tool. Running is far more effective. How many idiots have a rifle for home defense? How many truly can use a carbine, shotgun, or handgun for proper home defense? How many can truly defend their family, in the dark, with moving subjects, while not shooting the wrong person or getting shot themselves?
This appears to be an imaginary threat. If you live in South Central Los Angeles, sure, I can completely buy the argument. That place is fucked up after dark. However I can also buy the argument that it makes a lot more sense to sell your over priced property and move to a better part of the country with a cheaper cost of living. Live in Memphis? Move. New Orleans? Move. It makes way more sense to use your feet for self defense rather than a weapon.
Show me where lots of women are shooting rapists and murderers. It's not happening. Those few cases are far overshadowed by firearm accidents. They have done studies that show that those that have a firearm are far more likely to be injured by one whether in an accident or simply getting shot.
I don't define talking one's way out a situation as "self defense", and neither does the law. Talk is talk. "Self defense" is what happens when talk/avoidance is no longer an option.
As I stated earlier, the National Crime Victimization survey found that on average 47,140 people defend themselves with a gun every year from 2007-2011. If you have some evidence that the number of firearm related accidents/injuries outweigh this number, or that this number is wrong I'd like to see it.
Imaginary threat? I live in a medium sized town of ~35,000, college town. Crime rate is slightly above the national average, but nothing horrible. One night a couple of years back I was walking home from the library at 2AM, on a route I'd taken literally hundreds of times without issue. On my way back I passed by two black stereotypes, didn't think much of them at first, but they reacted rather interestingly to me. They started as I overtook them (I was walking slightly faster), looked at each other, then dropped back. So happens at this point I had to make a turn, so I did, and I noticed they turned very awkwardly to follow me. Now at this point I was getting concerned, but they were still maybe 40 feet behind or so. They followed me along the straight-away for about 30 more feet, then I heard their pace spontaneously double and they started to close. I had a heavy backpack on, no chance of running. So I held my pace, turned my head to let them know I'd seen them, squared my shoulders and made a show of shoving my hands into my pockets. They SLAMMED on the brakes and dropped back to about 50 feet. Didn't bother me for the rest of the walk.
There you have it, imaginary my ass.
Likewise a couple of months ago we had an armed robbery where 5 guys mugged and beat the crap out of a guy at an intersection I walk through every day.
Now granted none of this is a regular occurrence, and a couple handfuls of victims a year out of 35,000 is extremely low odds, but it does happen; and I was almost one of the handful a couple years back. Answer me this, do you have insurance, for anything? Because that's all my gun is to me, and I pay my premiums in ammo bills and range time.
As for that study you mention in your last paragraph, I assume you're referring this study (
http://aje.oxfordjournals.org/content/160/10/929.full)? All they did there is chase down death certificates to find out if people who had been shot owned guns. Turns out gun homicide victims owned guns more often than not. It means absolutely nothing when applied to any given individual. It's like saying someone who owns a car is more likely to drive drunk, simply because they have a car. It's technically true, but ultimately meaningless.
