You know you can empty a revolver when you want to? Oswald was seen at all times during the shooting of Tippet, and was followed to the Texas Theater where they were captured.
Obviously you can empty a revolver but that makes no sense in this case after you just murdered a cop.
BTW, of the four cartridges found at the scene of Tippetts murder, two were Winchesters and two were Remingtons — but of the four bullets found in Officer Tippit’s body, three were Winchesters and one was a Remington.
Again, several witnesses of the murder didnt describe or identify Oswald. At least one person saw a ‘heavy-set’ man. In fact there was at least one person who saw 2 men flee the scene in opposite directions.
Read the evidence! The Warren Commission released their conclusion but excluded a multitude of contradictory evidence that pointed to someone other than Oswald.
