Rocks,
Here is AZ, you do not have to get a license to carry a concealed weapon, but some idiots do it anyway, thinking that this gives them the right to carry in other states as well. Nevada used to recognize AZ CCW licenses, but not anymore, because there is virtually no training involved. In fact, they do not even go to the range or handle a gun to get the CCW license. In fact, they do not even have to know how to operate the safety device.
I see all too many people buying guns that have that kind of knowledge of them. I use tools for a living. At our company, no one gets to use a tool without training on it. Forklifts, power tools, ect. Yet we have people out there buying assualt weapons with no knowledge of the damage or dangers of those weapons. And, almost weekly, we see in just this one state, children getting hold of guns left out, and killing or injuring other children. Yet the gun nuts expect us to ignore all of that. Next year, if trends continue, there will be more people killed in this nation by guns than by auto accidents.
