Mike, it's simple: the mindset is gun=violence. Thus more guns=more violence. It is totally specious, of course.
Here in TN we have been trying to get carry allowed in restaurants that serve alcohol. Now, KY has had this rule from the beginning. And they have had no incidents I am aware of where permit holders got drunk at dinner, pulled the gun and started shooting. And yet I guess Tennesseans are more redneck, backwoods, and prone to violence than Kentuckians because the bill always gets shot down whenever it is proposed here. Makes no sense.
