My own experience
1. When I was younger(before I had kids) me and my old lady rented a home. I worked quite a bit so she was the one that put it all together. The first week we were there at about 2 in the morning I awoke to a man opening our bedroom door. He passed up the TV, playstation, her purse, and everything else of value we had. He went straight to the bedroom. Luckily I watched a little too much Unsolved Mysteries as a child and I might be a hair paranoid. I was sleeping next to the best weapon I had at the time, a shovel. I reached for it, bounded from my bed, growled something I cannot remember, and charged. The man bolted out the way he came in.
I will never know for sure what his intentions were. I don't know if he saw something or someone that he wanted. I don't know if he realized that a man that was willing to fight lived there. I can be pretty sure though that if I wasn't there with a shovel it would have ended differently. Now maybe you would argue that shovels offer sufficient protection but I highly doubt that she would have been able to stop him with just a shovel.
2. I have never ever ever had a gun accidentally discharge in my home or anywhere else. I don't know anyone that has.
Statistically speaking
A quick google search brought up this article from
Newsweek. I have chosen to link to it because it is from someone that seems to be at least leaning towards gun control. He points out that the estimates for how often a gun is used in defense depends on who you ask. Gun control advocates would say about 100,000 times/year and conservatives would say 2 million.
Even if we take the low estimate of 100,000 the argument that you are more likely to accidentally shoot someone than you are to use it for protection falls flat on its face.
The Law Center to prevent gun violence claims that "In 2010, unintentional firearm injuries caused the deaths of 606 people".
If you want to advocate for gun control than the likelihood of accidental shootings vs self defense is not the argument you should be using.
