1) "Homocide" rates include assailants justifiably killed in the commission of crimes. So your statistic is ambiguous at best.
2) Not all stand your ground laws are the same, and not all are like that of Florida.
No doubt there is a certain amount of built in ambiguity, if for no other reason than the cop that makes the report has, what should be a judge's discretion as to whether or not a crime has been committed, or if an arrest should be made, etc. but-----but two separate reports, one by Texas A&M the other by Georgia State University came to about the same conclusion: ""It could be that these are self-defense killings," he said. "On the other hand, the increase could be driven by an escalation of violence by criminals. Or it could be an escalation of violence in otherwise nonviolent situations."
But which is it?
Hoekstra checked to see whether police were listing more cases as "justifiable homicides" in states that passed stand your ground laws. If there were more self-defense killings, this number should have gone up. He also examined whether more criminals were showing up armed.
In both cases, he found nothing. There were small increases in both numbers, but it was hard to tell whether there was really any difference.
So if the numbers on justifiable homicide and criminals using lethal force don't explain the rise in homicide, what's causing the increase?
"One possibility for the increase in homicide is that perhaps [in cases where] there would have been a fistfight ... now, because of stand your ground laws, it's possible that those escalate into something much more violent and lethal," says Hoekstra."
