Some interesting preliminary research on stand your ground laws, such as the one George Zimmerman's lawyers will probably try to use to defend his killing of Trevon Martin in Florida. Early research apparently suggests the following:
1. The number of gun deaths goes up greatly after states pass this sort of law...
2. But the increase is not among justifiable homicides (people "standing their ground") and is primarily among Caucasians.
3. The best hypothesis I heard was that, under this law, white folk felt more justified in shooting each other because they were "standing their ground," even though they weren't. In other words, everyone thinks the other guy is in the wrong.
4. This relates to a skew propagated by the president of the NRA in response to the Sandy Hook shooting. It is inaccurate simply to divide up people into "good people" and "bad people." Most people are somewhere in the middle--good in some situations with the potential to do bad things in others.
There are situations where the average Joe just shouldn't have a gun in his hands.
