You make an excellent point and it's the point I was after earlier when I noted that having a chute to pull on the way down if needed would be priceless!
I have many safety devices that I don't use often. One is a motorcycle helmet. After 36 years of riding with one there was a day I needed it and it did exactly what I needed it to do!
I honestly don't like answering questions concerning my use of a weapon (because it's not their business) but needless to say that among family, friends, and neighbors a weapon has been used a few times to prevent serious injury or possible death.
Where the argument falls apart for many is that inanimate objects do not animate themselves and cause the problems that are being blamed on them. I guess some folks have weapons that sneak out at night and do bad things but mine never have.
Pilots train extensively (or should) to mitigate errors that cause injury and death to themselves and their passengers. I had motorcycle training to help me better understand how to be safe and survive when the going gets tough. Federal Firearms Instructors and other resources are available to teach the safe use of weapons. Like most tools they require good training from a competent instructor and regular practice.
Those that are afraid of firearms should not own one as it will hurt you. I also want to reiterate that I don't need the permission of anyone to use any means necessary to protect myself or my family as self preservation is part of the human design. That means I might use a firearm, a knife, club, brick, spitball, water balloon, etc.
