If you are thinking about shooting before you are thinking about making sure the threat is valid, you could very well find yourself in the position of being half cocked and blasting away. If the simple act of someone screaming wildly and walking around with their hands in their pockets leads you to immediately think about shooting them when you aren't there, then there might be a good chance you would act that way if you really are there.
And where is all this time your talking about to figure out its all a bunch of kids playing a joke?Nobody is suggesting going off halfcocked blasting away if a pin drops,nor suggesting even that i would have shot in this situatio after all i wasn't there.. but you have to admit this was a dangerous game they played and they should count their blessings one of them didnt get killed.
You seem to suggest that a CCW who did fire in this situation would be unjustified. Nobody knows exactly what they would do unless they were there.But the overall picture of a takeover robbery does lend itself to a very dangerous situation.
