I hope private gun ownership isn't evil or then I guess I fit the profile. I have only 2 rifles, a Winchester 94 30-30, and a Rueger 10/22, 2 pairs of nunchaku's . My neighbor and close friend works for Homeland Security (because of my past work history I have had FBI clearance twice in my life) and all I can say is our neighborhood is well protected, most of my neighbors have guns of some sort and our town has a very small police force, only 2 on duty at any given time. We also have a local State Police Resident State Trooper, my cousin is a State Trooper also.
The fact that anything can be used means that people must observe people. When Timothy McVeigh was seen blowing up barrels of horsemanure bombs that should have rung a bell.
In my town any type of gunfire that located in a neighborhood area is promptly reported. You must have 1000 feet from your border of your property to legally discharge a weapon, not being used for self defense. People here are vigilant. Everyone knows who belongs in town and who is out of place, our town Population is approx. 14,000 people. Crime is low, except for teenage type vandalism which is in the normal range (some graffiti) but no violent crime or fighting or gang activity.
Guns don't kill people, people kill people.
