You haven't got an argument to stand by. The crime rate in Tennessee is much higher then the crime rate in Wisconsin, despite 220K CCW holders. How can they be lowering the crime rate? Wisconsin has zero CCW holders and a much lower crime rate. You can't explain that with your urban/rural argument.
I do have an argument to stand on. It looks like you failed to read my analogy of the fast food restaurants. If I don't have an argument to stand on then please answer this question. You see three banks, each has a total of $5,000,000 each stored in them. One bank has a sign, "3 armed security guards". Bank two has a sign, "6 armed security guards". Bank three has a sign, "20 armed security guards". Now, if you are a desperate criminal, which of the three banks will you rob, assuming you don't know the shooting skills of the guards or the layout of each bank.
Would you rob:
Bank #1 with 3 Armed Security Guards
Bank #2 with 6 Armed Security Guards
Bank #3 with 20 Armed Security Guards
If anyone here says Bank #1, I do believe I have a strong argument on my side. This is logical and common sense. Yes, I agree there is many co-factors and just saying having more gun owners and conceal carry permits will alone lead to a low crime rate is absurd. However, to say that because Tennessee has more crime than Wisconsin, means CCW has no detering effect for crime is equally absurd.
You are comparing apples and oranges, comparing Wisconsin to Tennessee. I could just as easily compare crime rate in Lucerne, Switzerland to Nairobi, Kenya. Switzerland has much more liberal gun laws than any African nation, especially Kenya. Nairobi, has one of the highest murder rates in the world. The fact that Milwaukee, a city that has probably a similar demographic layout to those in Tennessee (such as Memphis), has more crime than any city in Tennessee may also be an eye-opener for you.
What we need to compare is Tennessee to Tennessee. Does having larger amount of CCW permit holders result in less crime in Tennessee as opposed to less CCW permit holders in Tennessee? I agree the co-factors must be taken into consideration.
I know a guy from Detroit who had a shootout with an armed man in his house. As soon as the burgaler saw bullets flying his way, he panicked like a chicken and took off. However, had this man not fired his gun, the burgaler would have killed him and his family. What was it that made the burgaler so afraid as to flee, I am sure it wasn't the gun, since a law-abiding citizen with a gun would not to deter crime, right?
Even if Tennessee has higher rural crime than other states, the crime rate in rural Tennessee is very very low compared to urban areas. It is true male youth commit more crimes. Socio-econic, cultural, ethnic and even religious views will also be a major contributing factor to the criminal element in the area. Despite these well known facts, that does not mean that arming citizens in these areas will not affect the crime rate. These criminals pray on the weak, not the strong. A purse snatcher will go beat up some old lady and run with her purse, rather than pick a fight with a 300lb bodybuilder to get his wallet.
I asked you earlier, tell me how many police stations or other facilities with high numbered of armed personnel have been robbed at gunpoint compared with civilian establishments where people are known to be unarmed. I am sure the Memphis PD has plenty of goodies in their evidence room. How come gangs of armed thugs don't go and raid it if they are so undeterred by guns?
Food for thought.
