I wanted my memory refreshed as to Oswald's movements after he left the SBD.
He was really a bad guy. Shot Tippett from across the hood of Tippett's car, then walked around and stood over him and shot him in the head.
Some months prior he tried to kill Gen(?) Walker with his rifle. At the time the cops had no leads but after the JFK thing they matched the bullets to Oswald's rifle.
They also pointed out he used to sit on his porch and practice working the action of the rifle. He was seen at a firing range shooting , some at others people's targets. And they said he was a good shot.
He was originally arrested for the Tippett murder, then linked to JFK.
One other thing.
He was an accomplished liar. Very cool under pressure.
Put me in the Oswald acted alone column.
To my way of thinking the only possible conspiracy would be the Cuban connection and there is zero evidence of that.
