Shoe on the other foot:
You decide you need to lose some weigh so you take up jogging. One day while making a lap, 2 black guys (or Mexicans, pick a minority) block the road in front of you with their truck and hop out with guns. You have another vehicle running up behind you at the same time. You gonna stand there and take whatever, or are you going down fighting?

We see on here constantly that you should never point a gun at something (or someone) you don't intend to kill. Fat boy drew down on this young man. He interprets that (correctly) as "this SOB aims to kill me." He chose fight over flight. I imagine in the moment, many of us would've responded the same way.

To attempt to find excuses for these 2 guys is to try to justify killing a black guy simply because he is black. There has been no evidence provided to support any other position.
