Fox News (yes, I know):

So-called justifiable homicides up from 32 in 2006 to 48 in 2010.

27 of those in Houston (wow! - I'm staying away from there!  Is this an effect of migration from New Orleans due to Katrina?  Not related to Stand your ground after all?

It's usually a "minority" person killing a "minority" person.

"Texas law...goes further than other states in allowing deadly force not only to protect property, but also to stop rape, arson, burglary, robbery, theft at night and criminal mischief at night,"

Alternet (a favorite on Nexus) - reporting a study done at Georgia State

"A working paper released this week found that states that have passed controversial “Stand Your Ground” laws actually ended up seeing more homicides after the laws were passed."

"“significant increase in the number of homicides among whites, especially white males.” - interesting given the Fox report above.

States that have Stand Your ground laws are....:

a higher percentage of black population

more likely to have a Republican governor

higher incarceration rates

more police officers.

more urban

higher poverty rate.

Those states are:

"Alabama, Arizona, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Montana, New Hampshire, Oklahoma, South Carolina, South Dakota, Tennessee, Texas and West Virginia" -

My first impression is, with the exception of New Hampshire, these are mostly very christian states as well.  I don't know if a statistical analysis would bear me out on that.

In a current Florida case, Tampabay.com, Stand Your Ground will be considered for a lethal drunken brawl, involving "a cat fight in a bar parking lot, women with stun guns and pepper spray, a sucker punch, and a dead man who was once notorious for his rap sheet as a 4-foot-6 fifth-grader". - the dead man having been recently released from a psychiatric hospital after treatment for bipolar disorder.   Much of which was filmed on a cell phone.  The defendant claimed that "a crowd of hair-pulling, nose-punching women had created a lethal atmosphere" so he was justified in killing the man.

The legislators and governors who pushed these laws into place, seem to have a naive, comic book picture of white-hatted cowboys defending themselves mano-a-mano from unprovoked gun-tote'in attackers.  I don't think that's the real-life situation.
