there is no duty to retreat, even if you could retreat.
Many states have enacted so-called stand your ground laws that remove the duty to retreat before using force in self-defense. Florida passed the first such law in 2005, generally allowing people to stand their ground instead of retreating if they reasonably believe doing so will “prevent death or great bodily harm.”
I didn't say there was. I've been explaining this stuff here since Trayvon.
"Florida passed the first such law in 2005"
Florida wasn't the first. There's a long history of having no duty retreat. For example, California has the broadest "stand your ground" law, and has for a century.
