an LN has agreed more or less with my previous suggestion that Oswald could have carried a rifle in a carton box package around in Dealey Plaza and not arouse suspicion, given that William Castor did just that on Wed Nov 20/63
and since it is reasonably probable that Oswald could have been informed by Tuesday of the JFK motorcade route from overhearing discussion of such from those who DID read the Tues paper
And since Oswald DID have enough money to use a Taxi
Then Oswald could have taken Taxi on his Tuesday lunch hour to get his rifle wrapped up in blanket and return to Dealey Plaza and carry it to some other place from whence he would only need ONE shot to kill a stationary JFK making a speech
