For the people complaining about the "Stand your ground" law not being perfect......of course it isn't. What law accounts for every possible situation. Sure, maybe it can be tweaked to be better, but if the law required retreat, it could put innocent people even more in harms way. We live in a violent world, it would be nice not to need guns and laws like this, but innocent people need to defend themselves.
That said, whatever happened in this case is absolutely tragic. The evidence presented, although seems handpicked, points at this not being self defense.
