Some people say that using a gun as a threat is a stupid idea, that you had better not draw a gun except to use deadly force to defend your very life or safety.
erm, where do people get that idea? a drawn gun is a clear sign of danger to life and limb for whoever sees the bore end. People will usually back down to presentation of superior strength. Once the handful of dangerous looking punks have halted in their steps, retreat becomes a viable option. There's not a chance in the hot place that most of us could outrun a bunch of kids who spend their lives walking around looking for trouble and running like prairie dogs when they find it, especially if the intend victim is carrying a brief case, groceries, or even wearing bad shoes.
If one or a group of people present a threat that merits a show of force, you can draw the gun to use as a warning, and not have to use it. You can then visually clear the adjacent areas in case his droogs are tiptoeing up behind them. Then, run, walk, even fly away if you can.
"starter guns for the fat man's mad dash tactical retreat."
The first time I saw that, it was enlightening and I hoped that every person who read it would contrast it to "stand your ground" You don't have to, really, if you can just walk away. There is wisdom in that deeply buried under the humor.
Watched a movie once in the past. First guy said 'if you want to proceed you will have to go through me'. Other guy said 'maybe i'll just walk around you.'
