Good point John. He should have just stayed in a back alley.
That hindsight thing again. John knows about Brewer because he has studied the case. Oswald did not know that a sales clerk would be watching him.
C'mon Brian. Are you suggesting that a clerk being inside a shoe store during the day on a Friday would have been the least bit unexpected? He would have seen Brewer there just as easily as Brewer saw him. And yet, "careful Oswald" lingered there anyway. So was he being cautious just in case or wasn't he? It seems like he was only cautious when it fits your narrative.
Not even to mention how this careful guy supposedly hung around the Tippit crime scene emptying his gun and looking at people in the face. Whoever this guy was, he
wanted to be seen.
