From Dan's post:
Here is the actual jury instruction read to Florida juries prior to the legislature’s enactment of Stand Your Ground.
“The defendant cannot justify the use of force likely to cause death or great bodily harm unless he used every reasonable means within his power and consistent with his own safety to avoid the danger before resorting to that force.
The fact that the defendant was wrongfully attacked cannot justify his use of force likely to cause death or great bodily harm if by retreating he could have avoided the need to use that force. “
“If George Zimmerman was not engaged in an unlawful activity and was attacked in any place where he had a right to be, he had no duty to retreat and had the right to stand his ground and meet force with force, including deadly force if he reasonably believed that it was necessary to do so to prevent death or great bodily harm to himself or another or to prevent the commission of a forcible felony.”
