The shover established his thugness with his behavior, the unexpected sudden violent push to the ground, not his skin color.
As for The National Felon League? Look at the extensive criminal histories of so many of the players.
So the shooter was only 47, 19 years older than his 28 year old attacker but not elderly. He was of smaller stature and slighter build and suddenly violently pushed to the ground unexpectedly. McGlockton could have come up, verbally addressed the man to move along and if the man did not move perhaps taken the man by his elbow and ushered him away. But he obviously did not. He suddenly and unexpectedly violently physically attacked him.
Very sad for his three illegitimate children with his lying girlfriend.
