Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

I came upon this very clear rendering of the Moorman photo. This may be the clearest I have ever seen.  What's crystal-clear is that the tool box is deeper than the front wheel. If not, then that bike is being driven into the curb. 

Compare it to the line of the limo or the line of Chaney's bike (although granted, his, lacking a tool box, looks more like a riding lawnmower). 

The front wheel is the the front wheel of Martin's bike, and that's why it isn't in line with the tool box of Hargis' bike.
