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

The thing about that little arrow of Lovelady's is that IT IS DRAWN AT THE EXACT SAME ANGLE AS FRAZIER'S.

THE EXACT SAME ANGLE. Do you see that? Why do you think that is? It's because Lovelady took his cue from Frazier's arrow. It influenced him. Not where to draw it, obviously, but HOW TO DRAW IT. He drew his arrow the same way Frazier drew his.

He could have drawn it vertically down. He could have drawn it horizontally over. He could have drawn it diagonally but from the other side. But, he ended up drawing it diagonally and at the same exact same angle as Frazier. It was a tandem thing.

That is Lovelady's arrow.
