This Marissa Alexander case has nothing to do about race or stand your ground. Both were irrelevant in her case.
The one issue her case does bring up, though, is Florida's 10-20-Life law. As a general rule, I'm not a big fan of minimum mandatories, especially in drug cases. However, I have always been a big proponent of this law and I think other states should draft similar legislation. Given the easy access to guns in our country, I believe we should absolutely come down hard on gun crime. With one exception, however. The charge of aggravated assault should not be included. I have always had difficulty in justifying including this charge within the 10-20-Life construct.
Aggravated Assault with a Firearm carries a 3 year minimum mandatory sentence. In my opinion, that's fair. You point a gun at someone with the intent of instilling fear into them, you should get at least 3 years in prison. However, if you fire the gun that should not trigger the 20 year minimum mandatory. The reason why is this - if you fire a gun with the intent to injure someone then you wont be charged with agg assault. You'd be charged with attempted murder, and I'm fine with the 20 year min mand in that scenario. If you fire the gun with no intent to injure, then the intent behind the crime, to me, is no different than the original agg assault charge which carries the 3 year min mand.
