When Oswald got to Frazier's house Oswald walked straight past the back door, opened Frazier's car, put his package in and then went back to the back door to wait for Frazier, why?
Wouldn't most people who were just holding their lunch just go to the backdoor and simply wait for Frazier?
Why did Oswald feel the need to hide his package ASAP and then double back to where he started?
And btw, the partition between Linnie Mae and Frazier's car was made up of slats and was not a solid wall.
