I spoke to Mr Attoryney last night. His advice was not to play that short of breath gambit becuase it can be used against you in that you are admitting to not being of good health. Imagine getting grilled on just when your health was having problems and did it contribute to your lack of good judgement in the shoot. What “lack of good judgement?” Well, you did admit immediately after the shoot that you needed medical care.
I suspect that if you were afraid for your life and had to shoot someone, you might really be short of breath or lightheaded. Adrenaline dumps are really something else.
