You can or should draw when you are legally allowed to and/or you feel that you are in danger of grievous bodily harm.
Regrettably, but absolutely correct.
That doesn't mean that you mustshoot.
Then what did you draw for?
Challenging the offending individual with a gun is legit based on the actual situation if you meet the test of being able to use lethal force...
...and can prove it to the satisfaction of the particular officer who may soon show up.
Officer Friendly will decide that, not you.
You shoot based on what actually happens. It is conceivable the threatening individual will give up or go away...
... and dial 911 at the first opportunity to accuse you of brandishing.
Unless, you are one of the I wanna shoot somebody crowd.
or the I'd rather buy a Lexus or install a swimming pool than pay a lawyer tens of thousands of dollars crowd.

Believe me, I'm the last guy in line in that "wanna shoot somebody" crowd. But I don't want to be seriously injured or killed and I don't want to spend the next three years in a courtroom or preparing to go there, let alone the money I'd have to pay a Beverly Hills-priced lawyer to make sure I remained free (or at least out of jail).
The problem I have with showing a gun you don't use is this, and there have been cases to back me up. In fact, one case involved the "brandishing" of not a gun, but a holster.
When you show your gun, by definition the viewer sees it. Now he can say two things he couldn't say before you showed it. First, you have it. Second, he can describe it.
If you aren't first to call 911 or you aren't as good a storyteller, or for any number of other reasons, he should somehow convince a cop that you simply got mad and "pulled" a gun on him that he can describe, you could lose the immunity from arrest (and therefore prosecution) and civil action that Florida law provides you when you are able to show or convince the police that your actions were due to your fear of imminent death or serious bodily injury. Such a situation might arise when the scene suggests it and you are the only one in any shape to do any accusing.
So while it's true that the statutes do seem to say (I haven't read them in a few months, so I'm maybe winging it a little here) you can brandish, in so many words, but not have it called use of deadly force (for which, I think, you have to point the gun or fire it in the general direction of the bad guy) if you can show that you did it defensively, sometimes what you see as a cut and dried situation is a little more murky to the responding officer. Keep in mind that cops are NOT lawyers and they frequently don't know the law. They'll write the report based on what they think happened and what they think the law is and arrest or not accordingly.
Now, the in Florida, the way I understand it, the stakes, while they do not directly include your home, are pretty high. While suing your home out from under you is not easy in Florida, hocking it to pay to remain out of jail might have the same effect.
So, read'em, both the self-defense (homicide) statutes and the weapons and firearms statutes completely and try to fit them together. My understanding is there hasn't been too much case law since last year, and since the ostensible reason for the changes was to codify case law, reading the laws is probably enough. I try to read them every 2 years, but as you can see, maybe I should make it every year.
Also, every gun shop (with a range, can't speak for pawn shops) I have entered has available copies of a very good book about every aspect of self defense and gun law. I can't recall the name, but it was green before the 2005 changes and is tan now and about twice as thick. It is written by a lawyer and is loaded with examples. Buy it and read it next trip to the gun shop.
