Without commenting on how it relates to carrying a second (or third) magazine (or clip!) for your primary weapon, I'd say that many will respond correctly and cooly to a crisis situation. That isn't to say they will do so to every crisis situation by any means but one can be exposed to a crisis situation under many circumstances. Usually we refer to those as "close calls." Think of all the things you've experienced, probably, as a driver. You really didn't train for any of them, I suspect. Same with emergencies in the home.
Others, however, either go to pieces or freeze up. And I suppose, there just as many situations that are not clearly crisis-level emergencies. Those become a little more difficult but life is filled with more grey than black and white. But basically, I give the guy on the spot more of a benefit of the doubt and at the same time, I wonder if more and more training (for a civilian not a law enforcement officer) will necessarily result in a proper response.
