My Summation based on locale and parties involved
Young brother walks into gun shop armed and is immediately profiled and approached by red neck owner....
cac: Say boy, sign says no open carry or loaded weapons allowed. Imma have ask you to leave
Brother: All these fuckin cacs in here (***gestures to all the honkeys in the store packing heat) open carrying and you come to me wit the bullshit cac!?
cac: This aint a discussion boy, im telling you now, leave or else (***hands motioning toward his holstered weapon....)
Brother: Or else what cac! Fuck you reaching for!?
cac: (***Reaches for weapon)
Brother: (***Draws in self defense)
cac: Lets off shot
Brother: Rings back and drops the cac
cac patrons: Already locked and loaded, begin to fire down on Brother and sibling as they retreat to exit.. hitting both brothers (one fatally), and innocent customer (fatal shot) near doorway.
