You're joking, right? The President was just killed so they immediately traced the rifle which led to Kleins and the Kliens microfilm led to Hidell's PO Box which was owned by Oswald, Oswald worked in the Depository building and Oswald was also seen killing Tippit, see how this works, detective work is one logical deduction one after another.
All the evidence leads to Oswald.

You're responding to classic conspiracy thinking: evidence that points to Oswald's guilt must actually be evidence of his innocence. Why? Because it was simply too easy to gather.
The more evidence of his guilt is more evidence of his innocence.
The reason Oswald left the building so quickly, the reason he was on the run, the reason he showed no interest in the event, the reason he shot Tippit, the reason he fled into the theater was because he shot JFK. All of those obvious actions indicate flight.
No, to the conspiracy believers it indicates conspiracy to frame an innocent man.
Up is down and down is up.
