All an agressor who is attacking you should ever see if the application of deadly force is justified are muzzle flashes as you conduct a failure drill on their person (2 to the chest and one to the head as fast as one may apply it accurately).
A scornful look or sneer or being 6 feet four inches tall and 312 pounds is sufficiently intimidating.........not a firearm brandished. Which BTW may land one in the same cell of ones agressor in most cases.....
Stay Safe, carry intelligent , shoot smart as a last resort !
