Female heterosexual checking in here.
Unlike most of the posters in this thread, I have had the need to physically defend myself. In the past, I have experienced
One attempted rape. Result: I have a scrape on my neck and a couple of bruises. The would-be rapist had broken bones.
Two knife attacks. Result: I disarmed my opponent and beat the living shit out of them.
One assault-from-behind. Result: I had a broken rib and spent a few minutes unconcious My opponet required about 150 stitches to put their face back together.
I have never felt a need to walk around with gun, knife, pepper spray, or other weapon. I’m quite dangerous even when “unarmed”. (My oldest sister used to teach self-defense. A good kind of big sis to have.)
I have lived in Detroit, Chicago, and Gary, Indiana, all of which have been declared "murder captial of the world at one time or another. I have found that avoiding trouble, followed by a high-speed run, is the best defensive option.
Currently, about the only place I feel a need to watch my back is Chicago, where I work - but handguns are outlawed, and with the heightened security in buildings over the past year carrying anything that could be a potential weapon is problematic. So it’s just as well I don’t feel a pressing need to carry one.
Where I live, however, guns (and other things) are legal.
That said - a lot of my decisions in this area are based on the fact that I have had defensive training and I am stronger than most women my size and age. If I were disabled, or when I become older and possibly frail, I may choose different options.
I don’t carry a gun because I realize my ignorance about them (never owned one, fired one, do not come from a gun-owning family) and I do not have the proper education and training to safely choose, maintain, or use such a weapon.
I don’t carry a knife because I have learned that it can be surprisingly easy to have it removed from your possession. Also, you do not need a knife to block a knife attack.
I don’t carry pepperspray because firing upwind or having it taken from you can result in YOU becoming disabled as opposed to your attacker - although if my neighbors don’t control their dogs better I might start carrying it on bike rides.
I am a strong supporter of 2nd ammendment rights, even if I have never owned or fired a gun of any sort. It’s an option. For some people guns are a good choice. For others they are not.
My husband, for instance, has a disability that makes it impossible for him to run away from trouble. He has, at times in his life, carried weapons. I’m cool with that - his options are different than mine and he decides accordingly.
By the way - the fear that defending yourself with force, even deadly force, automatically results in long-term legal complications is somewhat exaggerated. My husband was attacked in Chicago and defended himself with a car door and with a knife that unquestionably was beyond legal limits. However, the knife was a tool-type knife, not a hunting knife, which he had as part of his working toolkit (he could have just as easily used a screwdriver, for instance). In other words, it was clearly not primarially a weapon, but rather a tool that could be used as one. Also, he had clearly acted in self-defense, and was disabled, so was more vulnerable than an able-bodied person. Once the attacker fled, he did not pursue. The cops questioned him briefly on the spot, then let him go and there were no further complications.
The point being you DO have a RIGHT to defend yourself - even with deadly force should that be required. You can’t shoot someone in the back - but if an armed attacker is advancing on you and you physically can’t flee you certainly ARE permitted to defened yourself in a physical manner.
Could I kill someone? If it was a matter of life and death - yeah, I could. I wouldn’t enjoy it, and I’d much prefer an alternative, but if I HAD to, yeah, I could. But I want to avoid such a situation entirely.
A good self-defense education - not just a one-day seminar but an actual course of study - is the most beneficial in my opinion. Something that teaches what to look out for, what to avoid, and gives you multiple strategies. The key is to use appropriate force so you avoid excessive force. “Appropriate” is what gets you out of trouble with minimal danger to all involved. For example, when I was almost raped I did NOT stand around continuing to beat the crap out of the almost-rapist - when he hit the ground I ran. I used the necessary force to extricate myself from danger - I did not attempt revenge, retribution, or any of those other concepts that can cause you legal trouble. Now, if the person in question had held a knife to my throat or a gun to my head I might have opted to risk rape rather than death - but that’s not the situation I was faced with. If it had been… well, if fighting an armed attacker will likely get you killed, opting for a painful but non-deadly alternative might make more sense. Again, it’s better to avoid the need to make such choices in the first place. Most of all you need to learn to think quickly because each danger situation is different and you have to make the best choices you can at the time, based on the situation you are dealing with. You learn that by lots of role-playing and practicing various sceanarios.
