I wonder how many people have realistically placed themselves mentally in that situation. Put a timer on this process. You come home without a care in the world. Get pounced IN YOUR HOME by 2 assailants and according to the police chief, are beaten, bloodied, and bruised. You are then picked up and body slammed to the ground, breaking your collar bone. You manage to grab a weapon and fire, fire again, give chase and fire 2 more times. End of incident. The whole thing occurs literally in a matter of seconds.
Where is your adrenaline? What is your level of fear response (fight or flight)? At which point were you able to logically apply calm and reasoned thought?
