I don’t know why this guy is looking at his shoes while this racist POS rails at him. If it were me, my eyes would be locked on his while just drilling him with a stone face...and possibly a small wry smile...just waiting for him to get in my face. One touch and he’d be dead.
Maybe because the guy was with his family.
Looking straight in the eyes at a predator is seen by the predator as a challenge. He didn’t want to give the predator as reason for start throwing fists or worse.
Now if he was alone or the guy hit his child, different matter.
