Yeah, in that situation, my adrenaline system would be bubbling over as well, though I am certain there would be rust and crud on my gears.
I periodically run through scenarios with the wife so she doesn't have to do any heavy thinking to react in a way to protect herself from bad guys and/or LEOs if she ever finds herself in a situation....if it's a bad guy and she feels the need to shoot - it's keep firing into center mass - and follow the perp down to stay on center mass - until the slide locks back and then pop in the spare mag before checking to see if she has need for further action...and to make sure the weapon isn't in her hand when "help" arrives...let them know where the weapon is, status of being loaded, and keep her hands shoulder high throughout w/o reaching for it and let them remove it from her possession.
No other statements w/o a lawyer present.
