Oswald took his rifle - you really think it was his lunch? - and shot JFK.
“you really think it was his lunch?” Does not constitute evidence of murder.
Neither is “not being interested in what happened”.
Anyway, if someone doesn't believe the 8-10 witnesses who saw Oswald shoot Tippit or leave the scene
(and the other physical and circumstantial evidence) I doubt you'd accept witnesses who saw Oswald go down the stairs.
False equivalence. People who worked with Oswald knew who he was and saw him every day. They’re not being manipulated by unfair, biased lineups or an unfair, biased photo showup. Besides, only one person saw anybody shoot Tippit: Helen “didn’t recognize anybody in the lineup” “utter screwball” Markham.
And if powerful evil groups did pull this off you can be damned sure they would make Norman and Jarman and others say they saw that very same thing, Oswald going down the steps.
And there you go again. The omnipotent conspiracy that I just dreamed up in my head would make it look like Oswald did it, and it doesn’t look like Oswald did it. Therefore, Oswald did it. This never gets old.
