Here's an example of the unintended consequences of the stand your ground law as it relates to florida and other states.

In florida there was an argument during a playground basketball game between two youths. The argument got loud with threats going back and forth between the two. Basically they were in each others face.

One youth decided to do a preemptive strike against the other youth, hit him and unfortunately killed him with one punch.

The youth was not charged in the death based on the stand your ground law.
