Pretty much everyone I know in the gun community would say that all the situations you mentioned are ones where you better not draw your gun.

As another commenter pointed out, drawing your gun in those situations is usually a pretty serious crime (supposedly even showing that you're carrying a concealed gun to ward people off is a crime in some jurisdictions - I haven't verified).

So not sure what the point of your comment is. You're describing scenarios that are irrelevant to the thread.

Oh, and just BTW, lots and lots of cases of people acting like you ending up dead. Acting appropriately in dangerous situations doesn't mean you will come out on the better end.
