Stand your ground is one of the silliest laws ever.

This morning I was in the center lane and the sign said "Right lane ends". Some jerk in the right lane goes tearing past. I could have forced him into the ditch but I chose not to. If you deliberately contribute to an accident, it is not an accident, and you are equally guilty.
If you carry a gun and some thug demands your wallet at knife point you have the right under Stand your ground to shoot him. But, would you? An eye for an eye means just that, no more, and a life for a wallet breaks that rule.
