Well go ahead and demonstrate who else besides Oswald was seen with a rifle in Dealey Plaza?
Loaded question. Demonstrate that
Oswald was seen with a rifle in Dealey Plaza. All you've demonstrated is that a guy (eventually) claimed that he saw Oswald with a rifle. Just like there's another guy who claimed he saw a guy with a rifle behind the knoll.
And then explain how Oswald's rifle with his prints and shirt fibers were found on the same floor?
"Oswald's rifle". LOL. And fibers that were similar. LOL.
Then explain why the Sniper's nest area where Oswald was seen was covered with his prints?
Uh, his job was to get books out of boxes?
Then explain why Oswald left the building immediately?
On a day when all the employees were dismissed?
Then explain why Oswald felt the need to kill a Police Officer,
Demonstrate that Oswald felt the need to kill a Police Officer. Because "utter screwball" said it was him after saying "no" six times?
the first Dallas Police Officer killed on duty by gunfire since 1960?
How is that even relevant?
Then explain why Oswald tried to kill more Police at the Texas Theater?
That claim has been thoroughly debunked. Repeatedly. There's no evidence that Oswald tried to kill anybody at the Texas Theater.
Btw this time please support your opinions with evidence, k!
Why, you never do. You just make claims like "Oswald's rifle" over and over again.
