It was impossible for Oswald to even be at the site of the killing, unless he was also an Olympic sprinter.
You know that is bullshit, right?
President Kenedy was shot at 12:30 CST in Dealy Plaza. Officer Tippit was shot 45 minutes later at the intersection of 10th and Patton. At 12:40, Oswald then boarded a city bus, but because of traffic got off and took a taxi to his apartment. He left there just after 1, putting on a jacket he had not been wearing that day and was seen by his landlady walking south on Beckley.
Ultimately in a little under 15 minutes walking just under a mile to 10th and Patton where the confrontation.
Now let's take just the concept that he did not do any of that, but simply ran the distance from the TSBD to where Officer Tippet was. That is actually a distance of under 3 miles, even if he had stayed on city streets and not cut across parks. Do you really think it would take an "Olympic class sprinter" to run 3 miles in 45 minutes? I call pure bullshit, I know for a fact that is bullshit.
Oswald was a Marine, and part of the requirement was for him to be able to run 3 miles in 28 minutes or less. Well under the 45 minutes he had. And while not part of the actual test, Marines often train for PT tests in "Boots and Utes", or in combat boots and utility trousers. Once again, doing 3 or more miles in a half hour or less. And that is not even close to "sprinting", just a moderate jog for a Marine.
I was never any kind of "sprinter", but my general 3 mile time was around 20 minutes. In the time given, I could actually make that run round trip.
Once again, you are showing that you know absolutely nothing about this, the distances involved, or the capabilities of Oswald (or indeed any Marine). But please, tell us all again how running 3 miles in 45 minutes requires an "Olympic class sprinter". Hell, I could do that today, and I am 56 years old. Without even running, simply at a very fast walk.
