I guess their point is that this is a bad thing? According to Sarah Brady's Bunch:
The new Florida Shoot First law eliminates the duty to retreat and allows a person not engaged in unlawful activity who is attacked in a public place to "stand his or her ground" and use deadly force if "he or she reasonably believes it is necessary to do so to prevent death or great bodily harm to himself or herself or to another person or to prevent the commission of a forcible felony." Thus, even if the shooter could have safely avoided the threat by walking away or seeking refuge elsewhere, the Shoot First law permits him to shoot the assailant and gives him immunity from criminal prosecution and civil suit if he does so.
So, the standard liberal answer: Run Away! Cave in! Don't stand up to "evil"! It is just a difference of opinions, anyway, not worth fighting for, killing for, or dying for. It figures that they don't understand Iraq, Afghanistan...and are working to blow it in Iran. No wonder they look with shame on our actions in WW2, Vietnam and Korea. Either honor is worth more than life, or life than honor. How you answer that dilemma grows directly from your worldview.
