Stand Your Ground
Rising numbers of civilian justifiable homicides across the US are closely linked to states with both weak gun controls and stand-your-ground laws, according to a Guardian analysis of FBI and other data, which show a 25% increase in such killings since the controversial self-defence laws started being introduced around 2005....
Dan Gross, president of the Brady Campaign, said: "This research demonstrates a fundamental point. Stand-your-ground laws are dangerous on their own as a mentality. But when combined with weak gun laws they become a recipe for tragedy."..
But Gary Kleck, a criminologist at Florida State University,...said that one desired effect of SYG and the right to carry (RTC) laws was to deter violent criminals and reduce violent crime. In an email response to the Guardian's data, he pointed out that violent crimes had fallen.
"In 2006, the rate of murders and non-negligent homicides (all the criminal homicides that the FBI counts) was 5.8 per 100,000 population; in 2010 (the most recent year for which data are available), the rate was 4.8 – a 17% decline in four years. The robbery rate also declined by an identical 17% over the same period, from 31.6 to 27.5."
Kleck said: "The decline in crime that paralleled the enactment RTC and SYG laws cannot be considered proof of the effect of these laws. Indeed, I think RTC have no net effect on crime rates. My point, rather, is that these are the same kinds of correlations concerning CJH increases and enactment of these laws that your analysis has produced, and are equally ambiguous in their meaning, and equally relevant to a consideration of the effects of these types of laws."
So crime down, murders down, and justifiable homicides up as citizens get armed but don't draw any conclusions. But I might unscientifically privately.
