I have never been in any situation, camping or at home or traveling or doing my daily activities, where I needed a gun or any other weapon to protect myself or those I was with. I do not know anyone who has ever needed a gun in a situation, however I know many who believe they need a gun because of a situation that happened even though it was handled successfully without a gun.
I agree with those who state if you are not prepared and trained to use the gun, then don't have it. And if you are properly trained in using a gun, then you should also know that it is not a security blanket - it is a weapon. Having a gun doesn't make you safer, and thinking that way will find you in a situation that you could have easily avoided.
Situational awareness, the willingness to leave rather than escalate a problem, and understanding the repercussions of your decisions before you need to make them, will do more for your safety than simply "having a gun".
I also don't believe a gun is like insurance or seat belts or fire extinguishers, etc. These things are to recuperate, prevent injury, etc., from an event. A gun is to stop another PERSON from doing something. Having insurance or a fire extinguisher, or using a seat belt, will not destroy another person's life. Using a gun will. You need to be willing to take that responsibilty if you are going to carry a gun.
