The Stand Your Ground law doesn’t apply in this case at all.
Have a gander here:
a person is justified in the use of deadly force if (1) He or she reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony (Florida Statutes, Section 776.012). http://www.myfloridahouse.gov/FileStores/Web/Statutes/FS09/CH0776/Section_0776.012.HTM

The Stand Your Ground law only applies to home invasion or car jacking.
What we are witnessing is a massive disinformation campaign put on by Obama and Co. Its goal is to re-elect Obama, but also to attack gun rights in general.
Stand your Ground does not only apply to home invasion and car jacking. If you are walking down the street and confronted by armed thugs who are attempting to mug you, you have the right to defend yourself.
