Any sane person will walk away if that is possible, but the "duty to retreat" is often used to prosecute people who truly didn't think they could run away. (Do you really think you are going to "walk" away from a rapist, mugger, or whatever flavor of monster you dealing with?)
Since they love to bash Florida, lets take a look at what they have to say about the Sunshine state.
A clear result of the Shoot First law in Florida is wide disparity in the way cases are handled by different police departments. In some shooting cases, there was no investigation at all, while in others, detectives investigated for up to 20 hours.Despite their insinuation to contrary, justifiable homicides are pretty rare in Florida. In some cases, it is clearly self defense. (Several yahoos break into your home in the middle of the night, and that kind of thing versus a more questionable shooting.) So some shootings will be investigated, and some are clearly justified. They seem to think that the personnel in Florida Law Enforcement should waste time on clearly justifiable shootings just so everyone gets their "20 hours" of fame. Or whatever.
