15. key syg findings wrt firearms

The journal JAMA Internal Medicine published a study in November 2016 that found that firearm homicides increased after the 2005 passage of the law in Florida. That’s a narrower measurement than violent crimes overall, but the findings shed some light on the issue.

They looked at trends for firearm homicides in Florida between 1999 and 2014.
It found that after the "stand your ground" law took effect in October 2005, rates of homicide by firearm in the state significantly increased.
"These increases appear to have occurred despite a general decline in homicide in the United States since the early 1990s," the authors wrote. And states without a "stand your ground" law that were studied — New York, New Jersey, Ohio, and Virginia — saw no such uptick.

"Our findings support the hypothesis that increases in the homicide and homicide by firearm rates in Florida are related to the ‘stand your ground’ law,"

Our (Politifact) ruling: Referring to the year that the "stand your ground" law passed, Baxley said, "What has happened since 2005? We’ve seen violent crime continuously go down."
Crime has gone down significantly since 2005, though "continuously" is overstated. Moreover, it is hard to pin the cause of the decline on the passage of the "stand your ground" law, since the decline in Florida has been mirrored on the national level. If anything, firearm-related homicides may have increased after the law’s passage, according to one peer-reviewed study.
We rate the statement Mostly False.
