44 Amp, I think that is a bit of a red herring. As with Texas and their initial CHL program, people indicated this, but it just wasn't true. People said for years that crime dropped in Texas after the CHL program started, and it did. In fact the CHL program was so good it cause crime to drop even years before it went into practice! Never mind that violent crime was going down all over the country and had been for years.
If fact, in 2006 in Texas Commissioner Jerry Patterson published a nice article talking about how Texas CHL's lowered the crime rate in Texas. He was, after all, the senior author on the bill and it had been a decade of dropping crime rates in Texas since CHL went into effect in 1996. Cool, right? Stats prove it works.

What the Commissioner failed to tell people was that the Texas crime rate was also in a downward trend BEFORE the CHL went into effect. Apparently the notion of the bill was so powerful, crime in Texas started dropping in the previous decade, wavering back and forth a bit, then started its downward fall in 1992. But this just proves that pro-gun legislation and activities now can have such a powerful effect as to affect crime levels backward through time!!!!
But wait, there is more. Clear evidence that Texas CHLs reduce crime was so effective that when it went into effect in 1996, not only did the crime rate drop in Texas, but there was a national ripple effect that carried over to MA, CA, NY, and ME for several years(from Uniform FBI Crime Reports found online for each state). That is right, sir, statistics have proven that since the implementation of Texas CHL, the crime rates dropped in decidedly anti-gun states as well.
So what about Florida? Does the Florida example really hold water? No.
Here is the table, but it is better seen here...

Their numbers were up and down before 1987 and were down in 1987 and then dramatically back up in 1988, the very next year and up again the next two years. There is no clear indication that violent crime rates were impacted by concealed carry at all. Violent crime dropped more dramatically in 1976, 1982 and 1983, years before concealed carry than in 1987.
Most of the downward trend you see in violent crime after 1991 seemed to correspond with an overall downward trend in violent crime across the US.
