A glitch in the timeline....
January 28, 1962: LHO orders a .38 caliber Smith and Wesson revolver by mail.
Should be [if it indeed happened] 1963
March 9-10, 1963: LHO takes photographs of the home of General Edwin Walker, a right wing activist.
March 12, 1963: Ruth Paine visits Marina at the new apartment. Also that day, LHO orders a rifle from Klein's Sporting Goods in Chicago.
March 20, 1963: The rifle and the revolver are shipped
March 25, 1963: LHO picks up the weapons
Notice the remarkable 'coincidence' that the pistol [supposedly ordered two months before the rifle was] was shipped and then claimed on respectively the very same day as the rifle.
What are the chances of this?
Also note that presumably...Lee goes over to take pictures at General Walker's before any rifle to shoot him with ever arrives.
Why in hell take pictures anyway? What purpose would it serve?
