This doesn't even address the obvious... that Oswald was not close enough to Tippit to have blood "splattered" on his clothes, anyway.
A typical straw argument. The type of 'research' I expected.
How would you or anyone else know how close the shooter was?
A coup d' gras' shot at close range to the head----The police automatically postulated that it would not have been close enough to make it worth their while to examine for blood splatter?
Reverse investigation...accuse someone and then apply what didn't happen
