I'm betting you're going to have a hard time explaining how a citizen is going to "disengage" from a gunfight started by 2-6 other people.
Why don't you post an example of 2-6 other people taking a private citizen under fire outside of a drive by shooting? Your scenario is ridiculous. We don't live in Baghdad. In almost any self defense scenario you can name that happens here in the good old USofA your assailants will be trying to rob you or the business you are at. Not a lot of places where you are going to walk into a L ambush.
In that situation YOU my friend will most likely start the fight when you choose to resist. If
they start the fight you are probably injured or dead before you get a chance to get a round off.
If you think you are going to stand in the open and exchange fire with 2-6 bad guys then you must believe that you are bulletproof. I guess that's better then being unable to outrun a bullet
.
A deadly force encounter isn't like the "Lord of the Rings/porn tape" episode of "South Park".
And what would you know about a deadly force encounter? How much personal experience with them do you have?
You can defend yourself or you can put yourself at the mercy of people trying to murder you.
And you know they are out to murder you how? Again let me repeat, if they are truly out to murder you, you will most likely be dead or grievously wounded before you know what happened. The bad guys never signed the Geneva Convention nor do they play under the Marquis of Queensbury Rules. What have you done in your personal lifestyle that has made you the target of this criminal gang that's out to murder you?
Draw on someone who already has you covered with their weapon and you will most likely lose. Draw on a group of people who have you covered with their weapons and barring divine intervention or the greatest luck imaginable and you are almost certain to lose.
If they are herding you all into the freezer after they robbed the restaurant, then it might be time for desperate measures. Until the time you are certain that you have no other option it makes no sense to start a gunfight with several armed assailants. Comply, disengage...if you are carrying a large amount of ammunition simply because you are worried you might get in a protracted gunfight with more then one armed assailant and you don't live a criminal lifestyle where the odds of that happening are increased 100 fold then I think might want to rework your threat assessment.
