Well, I've had the opportunity to live 38 years in one of the absolute worst states for firearm laws, (Illinois). And for the last 22 years in what I consider the best state in the union for gun ownership, (Arizona). It really wakes you up when you have a state with excellent firearm ownership laws, after you come from what amounts to a communist dictator state that legislates them to death. And who are now literally trying to legislate them out of existence.
Anything here Class III or AOW is signed off on without question, and the paperwork process does not take very long. Sheriff Joe Arpaio is the "Chief Law Enforcement Officer" for Maricopa County, in regards to Class III weapons. He inks the paperwork quick, and is extremely pro gun. Right down to forming "Armed Posses" out of citizen patrols. You can't ask for much more than that from your top cop concerning gun ownership.
We now have the right to carry either open or concealed without any type of permit. Which as we all know, is the way it should be in every state. This thanks to Jan Brewer our Governor, who is also very pro gun and pro Second Amendment. She also recently signed a law allowing concealed carry in bars. Something the liberals cringed at. To date there have been no drunken bar shootouts involving CCW, or anyone else legally carrying either open or concealed. You cannot be served alcohol if you are carrying.
I think if there ever was a state that proves more guns, along with very open gun laws, equals less crime, it's Arizona. About the only state that comes close is Texas. So I would bring up Arizona with your state Senator when you speak to him. And keep referring back to it in your discussion. The reason is it proves how well firearm friendly governments works. Also mention Illinois, which while being the most restrictive, is also home to the murder capitol of the United States, (Chicago). It's always better if you give positive, as well as negative examples in your discussion. Just bloviating about a pro gun point of view convinces few, if any. Facts are on your side if you compare the best to the worst. The stats. are easy to look up and offer as proof. The better prepared with facts you are, the more convincing you will be. And at the same time impress the hell out of him with the fact you did your homework, and know of what you speak. Just preaching an ideology, be it pro or anti gun, is boring to listen to regardless of which side of the issue you're on.
