People act from their own fears and what they were taught. And of course their emotional state at the time.
Any person can at any time run into someone who is angry or frightened and if they have a gun then your life is at risk.
Years ago a Japanese college kid from Tulane looking for a Halloween party went up to the wrong house to ask directions. Man looked out saw someone that in his experience was the enemy and shot him. Did the kid deserve to get shot for walking up to the wrong house because he was lost. No
Did the guy plan to go out shooting every Asian kid he saw No.
But when a gun comes into the mix there is no turning back, no do over.
