They certainly do agree, but...the upward trend that occurred just after the passage of the SYG law is, in the consideration of longer term trends, just as easily attributed to a statistical anomoly as it is to any change in law. There are much larger upticks in the early and late '70's, which I would suspect have more to do with economic factors than any change in self defense laws; in case you forget there were economic perturbations in the years focused on in this study also. If the study documented a valid increase in homicides due to the SYG law then it's likely the increase would continue into the present homicide rate...but the fact is that the 2011 rate is comparable to the all time lows, in fact the difference is statistically insignificant. Was the SYG law repealed? Has an attempt been made to explain the return to normal homicide rates? Why have both the homicide and violent crime rates in FL been trending down generally (see the link I posted) since the uptick? Despite the authors' claims, I don't see this study as "empirical" in any way. YMMV.
