Threatened Use of Force
This video of the proceedings of the 2014 Florida Senate Rules Committee hearing gives some insight into the intent of Florida SB 448 (Threatened Use of Force), a law which creates an exception to the minimum mandatory sentence for aggravated assault under specified conditions. It is pointed out, in the video, that the 1999 10-20-life law was designed to help prevent the criminal use of firearms, however mis-application can lead to unintended consequences resulting in a miscarriage of justice.
The bottom line is that the same rules still apply to the citizen who needs to use force for personal defense.
