So I think the Vern Smalley incident is very different - I agree with the sentiment that Vern could have just let it go the moment he was cut off. However, that incident was laid to rest well near 25 years ago, and I will leave it with the courts and the jury.
After reading all the responses to the thread, it is obvious that drawing your gun in this situation would not have been, "proportionate or reasonable." However, in FL I am not sure if avoidance applies, and innocence definitely existed here as the victim driver didn't really start anything, he just did not respond when somebody behind him was screaming, "make the right." As for, "imminence," I do not know if that existed or not because the light turned green and the situation ended.
All 5 criteria for the use of any force (deadly or not) in self defense were not met.
I've also learned that, "brandishing," is a term used to define a crime. I did not know this before I made the thread. Which is why in my first post here I used the wording, "could you draw or brandish," your weapon.
I have never had a situation while I've been armed where I could have drawn my weapon. Which is strange, because I have had situations where I have been unarmed and I could have drawn a weapon. However, even in the situations where I was unarmed and could have drawn, I managed to walk away unscathed. Both situations though, where when somebody pulled a knife on me in a threatening manner, and even though they did not attack, I think its safe to say that if somebody within 3 feet of you pulls a knife and threatens you, you can legally draw your weapon.
I think after this thread I am ready to order my copy of Ayoob's, "in the gravest extreme." Unfortunately I have already have a zillion things on my plate this month, but I will read it sometime in December.
I really enjoyed all the responses so far, I look forward to continue reading the thread if it continues to develop.
