Well, how are you going to be able to link it hard unless you change nothing else and see a decrease? This isn't exactly a controlled experiment! I believe that it's more than "a leap of faith" but instead would be better described as a series of efforts, including more concealed carry, that has made a difference.
Should you wish to stick to your guns (so to speak) I think it is equally impossible to prove it has not made a difference.
So the the impossibility of proving a link proves your point? I know that you are smarter than that Pugs......

One thing to keep in mind, New York City has seen a dramatic drop in crime in that same time period, yet it has some of the most restrictive gun laws in the entire country. How do you explain that? I would say it is combination of effective policing, changing demographics and the gentrification of the city. Strict gun laws haven't had much of an effect in DC though, so I wouldn't say they work too much in many cases, though they do in some.
P.S. The Brady Handgun Violence Prevention Act was signed into law in 1993 and went into effect in 1994, maybe that helped?
