The shooter had no legal basis for firing that shot.
Now wait, any infantryman can tell you that setting up an ambush from behind cover and concealment and firing without warning is a tried and true method for killing the enemy in battle.
Oh wait, this wasn't Fallujah or downtown Saigon Cholon combat zones ambushing armed enemy combatants, it was an unarmed woman with a Trump banner as a cape sticking the upper half of her body through a broken window. Someone quick, give that marksman a medal, i'm sure pelosi will.
He is innocent because he is black.
