I think that the people screaming for stiffer gun control have never been forced to use a gun to protect themselves.
When my husband and I started dating, I had never pulled a trigger a day in my life. He purchased a few guns that I would be comfortable shooting and started taking me to the range. I went through a safety class and learned how to use several types of firearms well.
When Kevin and I got married and I moved in, the area he was living in was.... less than wholesome to say the least. And he worked night shift 2 weeks of every month. One night, around 2:00 a.m. a group of young boys tried to break into our home. I was alone and scared to death. I called 911 and announced to the burglars that I had a gun. Well of course my voice was shaking so they didn't take me seriously and continued to attempt to pry our doors open; some were at the front door and some were at the back. I yelled again and then slid the pump on our shotgun. It's a home defense weapon, identical to what the coast guard uses for close range shooting. The pump is loud and commands attention. They stopped in their tracks and ran. It turns out they were using screw drivers and knives to try to wedge the doors open. The 911 call center was less than 2 blocks from our front door. It took almost 45 minutes for the police to respond. If I hadn't had a gun and known how to use it, I shudder to think what could have happened to me that night. One of the boys even left a hunting knife stuck in the door jam. It had his initials on it and had been purchased at a local pawn shop. It was easy to trace and after a little pressure from our sheriff's department, he came clean and ratted on his buddies too. They all admitted that hearing the gun and knowing I was telling the truth was what made them stop.
You say there is no place for self policing? I beg to differ!
