What exactly do you think Oswald needed to explain? Why a shoe salesman thought he was in front of the shoe store and looked funny? Is that a crime in Dallas?
You're finally piecing this together.
Yep, Saint Oz needed to explain why a shoe salesman thought he was ducking the cops.
Turns out the shoe salesman was correct in his suspicions.
So Saint Oz made the very poor decision to throw a punch and pull his gun.
Which resulted in him getting his face caved in and arrested.
Kudos to the alert shoe salesman, Johnny Brewer.
Looking funny isn't a crime. If it was, you'd have been locked up a long time ago.
