"Insane reasoning is walking around with a gun because you are afraid that someone else with a gun might assault you."
Insane is pretending that someone else will be there to protect you and your family if the need arises. They most assuredly will not be.
Hedging your bet by staying out of trouble,and in large groups is a good start.
I had a coworker a few yrs back who lived out in the country on about 20 acres, so his neighbors were far away. His pregnant wife was home alone with their small 1 yr old child one early one morning while he was at work. She heard a sound at their back door and walked in the kitchen, and listened. She also saw the door knob turning slowly.
She fired her gun thru the kitchen door.
When the police got there, they looked around and no one was there. They did not believe her at first, until they realized there was no bullet hole in the outer screen door, which a spring keeps always closed unless someone is holding it open.
WHen my wife was 20, she was followed home one night and someone tried to break down the door to the townhouse she lived in. She had a purse gun,a small .25 cal and got it out, fortunately for her she screamed that she was going to shoot and the person left.
When I was small, we lived on the edge of town, in a rural area. My mom went to pick us up from school one day, for some reason my dad was off work and sleeping in their bedroom. He woke up and a man was standing in the bedroom, he asked what are you doing here? and the guy said "your wife let me in". My dad reached into the nightstand and pulled out his browning 9MM and the guy took off. The guy had unlocked several windows in the house , planning to come back that night.
THese are the type cases you never hear about.
You can be assured, that for every innocent life taken you hear about , plenty of other lives have been spared and crimes/rapes prevented by the presence of firearms.
